One day versus everyday

One summer, I worked as an

attendant at a convenience-

store/gas-station chain. My

duties were pumping gas and ensur-

ing some parts of the convenience

store remained stocked. As a low-lev-

el employee, I had a seemingly endless

list of superiors. I

had a supervi-

sor who was the

head gas-pump-

er/shelf-stocker.

He answered to

the store manager.

The store man-

ager answered to

a regional manager who answered

to a district manager. Or maybe the

district manager answered to the

regional manager. I can’t remember.

Anyway, one day the regional

manager (or maybe it was the dis-

trict manager) was supposed to pay

a visit to the store. You should have

seen how the place operated that day;

we went through more Windex and

Spic’n’Span in one shift than we did

the rest of the summer. Everything

had to be in the best possible shape

because apparently the store was go-

ing to receive a grade from the region-

al/district manager.

Unfortunately, I can’t tell you the

rest of the story because I wasn’t

there when the person handing out

the grades showed up. All I can say is

that the store’s staff remained intact

throughout the summer, so we must

have done OK.

What became evident even to a

naïve kid like me was the grade we

got that day did not represent every-

day reality. It represented our abso-

lute best eff ort for a very short period

of time. Unfortunately, that’s exactly

the phenomenon some of you might

be experiencing as users of structured

cabling systems.

A recent report from the Commu-

nications Cable and Connectivity

Association said that cables purchased

off distributor shelves failed to meet

the electrical- and fl ame-resistance

performance they claimed on their

outer jackets. Th e CCCA has been

quick to point out the brands are not

prominent in North America, and

each of the cables was made by an

off shore manufacturer.

But the deeper question is: Did

these cables ever really pass CMP/

CMR and electrical-performance

tests, and receive third-party lab rec-

ognition of that performance? If so,

then on the day these manufacturers

produced the cable to be tested, they

acted as if the district manager was

paying a visit. Everything from ma-

terials to processes was buttoned up

tightly for one day. Th en they went

back to their normal routine of far-

less-strict practices. On the other

hand, if they never went through

such testing, then these manufactur-

ers are fraudulently portraying that

they did.

We’re tracking this story now and

will have more details next month, as

well as on www.cablinginstall.com.

Today’s surveillance and broad-

band video applications are down-

right smart. Consider the following:

• Surveillance equipment boasting Internet

Protocol (IP)-addressable interfaces and

remote-control features off er signifi cant-

ly more security and fl exibility than fi xed

analog devices;

• IP-based systems record images in digital

format onto servers or hard drives, render-

ing the use of cumbersome tapes and cas-

settes for video storage obsolete;

• Community antenna television (CATV)

will migrate to virtually interference-free,

100% digital broadcasting in February;

• Emerging Internet Protocol Television (IP-

TV) technology promises on-demand, inter-

active, high-defi nition viewing experience.

Th ese applications are no longer suitably

supported by generic coaxial cabling; they

require smart cabling, too.

Growing smarter

Th e number of design professionals and

building owners choosing to support sur-

veillance, broadcast, and other video ap-

plications with their telecommunications

cabling infrastructure is climbing rapid-

ly. For example, according to a report from

Multimedia Intelligence (www.multimedi-

aintelligence.com) entitled “Internet Proto-

col/Networked Video Surveillance Market:

Equipment, Technology, and Semiconductors,” the mar-

ket for IP/networked video surveillance cameras grew

nearly 50% in 2007 to approach $500 million worldwide.

Th e market segment is growing at more than four times

the rate of the overall surveillance market.

In addition to replacing coaxial cables with slimmer

and more-fl exible balanced twisted-pair cables, the ben-

efi ts provided by using a structured telecommunica-

tions cabling network to support video applications are

numerous, including:

• Digital image quality;

In a typical analog CCTV surveillance-system topology, the video-distribution

hub or PVD integrator is located in the TR, and the system has a coaxial back-

bone. The interconnect patch panel is recommended for system fl exibility.

analog-camera implementations.

Planning for video

If you are not sure you need to support video now, the rec-

ommendation is to include in your cabling plans additional

twisted-pair channels specifi cally targeted for video applica-

tions to accommodate future system needs. While you may

not currently anticipate the need to support surveillance

applications with your infrastructure, you cannot ignore that,

with increasing safety and security requirements worldwide,

the surveillance industry is growing rapidly. According to the

RNCOS Industry Research Solutions study, “Global CCTV

Market Analysis” (www.rncos.com), the global CCTV mar-

ket—including analog and IP-based CCTV—grew at a com-

pound annual growth rate (CAGR) of 24.28% in 2007 over

2006. Th e same study forecasts the market to grow at a CAGR

of approximately 23% between 2008 and 2012.

Planning now for video-applications support makes good

business sense as well. According to a total cost of ownership

analysis recently published by Axis Communications (www.

axis.com), IP-based video systems always have lower imple-

mentation costs than analog-based systems if the cabling

infrastructure is already present.

All surveillance and broadband video applications,

Identifying the exact location of surveillance cameras at any

time during the cabling design phase, as well as develop-

ing a fl exible surveillance infrastructure that can accommo-

date device moves and upgrades, can be challenging. One

way to overcome this challenge is to piggyback surveillance

equipment access points with wireless access points.

This approach supports all surveillance topologies and

may be especially convenient for the management of

installations in which cable sharing is used to support up

to four 1-pair video signals over one Category 7/7A fully-

shielded channel.

TIA TSB-162 Telecommunications Cabling Guidelines

for Wireless Access Points and ISO/IEC 24704 Information

Technology—Premises Cabling for Wireless Access Points,

offers guidance on locating wireless access points in ceiling

spaces that can be applied to video-equipment access

points. A pattern of circles or grids with coverage areas is

defi ned, with the intention that work area outlets be cen-

trally located in their coverage area and MUTOAs centrally

located in their associated coverage area grid.

Although coverage areas may range in size from 3 to 30

meters, 12 meters is generally recommended as an opti-

mum size to accommodate most wireless and surveillance

applications.—VM

Juxtaposing surveillance equipment and wireless access-point coverage

This example of ceiling coverage areas for video equipment and/or

wireless access points is based on the TIA’s TSB-162 and the ISO/IEC

24704 specifi cations.

frequency channels, are capable of oper-

ating over lengths of twisted-pair cabling

greater than 100 meters. But maintaining

the TIA/EIA- and ISO/IEC-specifi ed ge-

neric maximum 100-meter, 4-connector

horizontal channel topology has numer-

ous benefi ts and is strongly recommended

for video-applications support. In par-

ticular, adhering to the generic topology

ensures that upgrades to future video ap-

plications will occur seamlessly, while

also providing the fl exibility that chan-

nels originally designed for high-speed

data support can be used for video if nec-

essary, and vice versa.

Pretty simple, actually

Video-deployment planning is sim-

ple: bring video-ready twisted-pair ca-

bling, in addition to data cabling, to each

work area or multi-user telecom-

munications outlet assembly

(MUTOA). For support of sur-

veillance applications in areas

where wireless coverage is pro-

vided, it may be convenient to

juxtapose video access points

with wireless access points in

the coverage area. (See sidebar,

“Juxtaposing surveillance-equip-

ment and wireless access-point

coverage.”) Th e advantage to this

approach is that the telecommu-

nications outlet is conveniently located

in the ceiling space where cameras re-

side, and video-equipment positioning

is more fl exible.

IP-enabled video devices are precon-

fi gured to accept the 8-position modular

plug interface and off er plug-and-play

capability with structured telecommuni-

cations cabling. Generic analog devices,

such as CCTV cameras, monitors, and

television sets, are typically confi gured

with coaxial BNC or Type F connectors

and require the use of video baluns to

enable transmission over twisted-pair

cabling.

Video baluns are used in pairs to con-

vert a 75-Ω unbalanced (i.e., coaxial) sig-

nal at the video-equipment interface to

a 100-Ω balanced (i.e., twisted-pair) sig-

nal and then back to a 75-Ω unbalanced

signal at the telecommunications room

(TR) or fl oor distributor (FD). Video bal-

uns are application-specifi c, such as for

CATV or CCTV, and may be confi gured

as single-port converters for use at the de-

vice interface, as single-port converters

located in breakout boxes for use at the

work area, or in 8- and 16-port video-dis-

tribution hubs for use in the TR. Video

baluns may also be integrated into high-

performance Category 7/7A patch cords.

CCTV surveillance applications

Video security can be an eff ective de-

fense in detecting threats as well as a

deterrent against future threats. CCTV

solutions are simple to deploy; consist-

ing of fi xed or remote-controlled cam-

eras, cabling, a recoding device, and a

monitoring device. While mandatory for

highly secure environments, such as gov-

ernment buildings, prisons, and casinos,

surveillance systems are now also com-

monplace in education, healthcare, indus-

trial, and fi nancial facilities.

This one-pair Category 7/7A TERA-to-Type F cord inte-

grates a balun.

The BNC (l) and Type F are common analog-

video connector interfaces.

Stewart Connector understands that specifying and sourcing quality modular connectors for premise and campuswide communications systems can be a tough job. Especially as technology, standards, and products continue to evolve. That is why we’ve engineered our plugs and jacks to ensure your networks’ superior performance... today and tomorrow.


Historically, CCTV systems were stat-

ic and deployed as analog systems sup-

ported by coaxial cabling. Enhancements,

such as the availability of cost-eff ective

baluns and IP-addressable devices, now

make surveillance solutions the perfect ap-

plication for operation over twisted-pair

cabling. IP-based surveillance systems have

the added advantage that they are signifi -

cantly more fl exible and “intelligent” than

traditional analog CCTV systems. A wide

range of structured cabling solutions sup-

ports video surveillance applications.

Th e simplest analog video CCTV con-

fi guration is a static system consisting of a

fi xed camera, twisted-pair cable, a pair of

video baluns, and a recording device such

as a digital video recorder (DVR). Th e

video baluns are BNC/RJ-45 connectorized

devices that transmit black-and-white or

color images over one pair (the pair ter-

minated on pins 7-8) of the twisted-pair

cable. Optional PTZ capability supports

the remote-controlled operation of the

camera and off ers more fl exibility than

fi xed camera systems.

PTZ in focus

Adjusting the focus, angle, and fi eld of view

without being present at the camera site

are all benefi ts of a PTZ-enabled system.

Structured cabling that includes PTZ-en-

abled baluns, which use only the 7-8 pair to

transmit video and PTZ commands, easily

supports this functionality. Because these

solutions operate over only one pair of a

4-pair cable, they represent an excellent

opportunity to take advantage of the

cable sharing capability of Category

7/7A fully-shielded solutions. (For

more information on cable sharing, see

Adjusting the focus, angle,

and fi eld of view without

being present at the

camera site are all benefi ts

of a PTZ-enabled system.

cents,” June 2006; that article is based

on the white paper, “Cable Sharing in

Commercial Building Environments:

Reducing Cost, Simplifying Cable Man-

agement and Converging Applications

Onto Twisted-pair Media.”)

Note that power must be provided

locally to each camera in both tradi-

tional coaxial and balun-based twist-

ed-pair CCTV camera deployments.

Depending upon the camera location,

providing separate power can range

from inconvenient to practically impos-

sible, and this need cannot be avoided in

coaxial implementations. Emerging PVD

(power-video-data) technology uses a

pair of powered video transceivers to ful-

ly support CCTV applications and elimi-

nate the need for external power cords by

transmitting video (one pair), power (two

pairs), and data (one pair) over one 4-pair

telecommunications cable.

PVD devices are not IP-enabled and

data is still collected on a traditional

external recording device, such as a DVR.

At this time, PVD transceiver solutions

easily accommodate the operation of

fi xed position cameras, which typically

consume less than 300 mA of power,

over 100-meter structured cabling

topologies. Be advised that the maxi-

mum distance supported by PTZ cam-

eras, which typically consume at least

600mA of power, is manufacturer-

dependent and may be less than 100

meters, causing these implementa-

tions to fall outside the scope of struc-

tured cabling. Th e good news is that

power delivery technology “borrowed”

from the emerging related IEEE 802.3at

PoE (Power over Ethernet) Plus ap-

plication Standard may result in an

improvement in the operating dis-

tances associated with PVD support of

PTZ cameras in the future.

In typical structured cabling imple-

mentation topologies for analog bal-

un-based and PVD video transceiver

CCTV surveillance systems, the video

distribution hub or PVD video integra-

tor is located in the TR and a coaxial

cabling backbone is provided. For max-

imum infrastructure fl exibility and to

facilitate adds, moves, and changes, it

is recommended to use an interconnect

patch panel in the TR.

CCTV over structured cabling of-

fers a distinct advantage over tradi-

tional coaxial cabling implementations

in that scalability and fl exibility are

In a cabling infrastructure supporting IP-based video surveillance, it is best to install a full cross-

connect in the TR for fl exibility with moves, adds, and changes.

tured solutions, cameras can easily be added or moved as

the system grows and needs change; however, this tech-

nology is not intelligent, meaning that while substantial

data is recorded, it is unlikely that the video is being actively

monitored. Events can be missed

and suspicious behavior can go

unnoticed when monitoring per-

sonnel are distracted or otherwise

occupied.

It is also important to remem-

ber that images collected over an-

alog surveillance camera systems

are recorded on bulky cassettes or tapes that must be period-

ically changed and will wear out over time. Image quality can

also be impacted by the limitations of the recording device. IP-

addressable surveillance solutions overcome these hurdles.

IP-based surveillance systems

IP-cameras and IP-based systems represent the fu-

ture of video surveillance. These solutions deliver

superior image quality, intelligent monitoring capabil-

ity, remote accessibility, and infrastructure scalability. Today’s

fi xed IP-cameras are all re-motely powered, and the use of an

IEEE 802.3af-enabled PoE switch is required. IP-cameras may

be fi xed or PTZ-enabled. Further enhancements, such as more

powerful PTZ capability, will become possible when the IEEE

802.3at standard is ratifi ed.

Th e advantage of an IP-based surveillance system is that

the camera acts like any other device on the IT LAN. Im-

ages are transmitted via Ethernet or wireless networks and

can even be accessed through the Internet. Th is means that

video feeds from multiple areas at multiple locations can be

monitored from one supervisory site. Furthermore, because

transmission is digital, the picture quality of an IP-camera

is superior to that of an analog camera. Audio transmis-

sion is also supported. Th ese capabilities result in IP-based

surveillance solutions being increasingly integrated into the

structured cabling network by companies with geographi-

cally dispersed locations, building access control systems,

and point-of-sale applications.

Network intelligence can also be built into the IP-based sur-

veillance system. Events can be monitored and alerts can be

delivered to report suspicious behavior that would otherwise

go unnoticed. For example, the activation of a motion detec-

tor, audio sensor, or anti-tampering mechanism could auto-

matically result in a short message service (SMS) text or e-mail

being sent to the security operator.

Instead of relying on external recording devices, IP-cam-

era images are recorded in digital format directly onto serv-

ers or hard drives. Video data can be stored indefi nitely locally

or transported to a remote location via the LAN or the Inter-

net. Real-time video transmission is highly compressed and

several compression options are available to maximize the trade-

off involving image quality, bandwidth, and storage capacity.

Commonly used compression techniques include MJPEG,

MPEG-4, and the emerging H.264 format.

Interoperability efforts

In what will be another advance for the IP-based surveil-

lance market, three leading manufacturers of IP devices

(Axis Communications, Bosch Security Systems, and Sony)

have created the framework for a forum whose purpose will

be to develop a standard that will specify interoperability

requirements for video devices. Once the framework was

established in late 2008, the manufacturers opened the

process to all interested parties. Th is step

will go far in removing barriers, such as

the perceived custom nature of IP-based

surveillance and concern regarding spe-

cialized knowledge required to install

these systems that have been a hindrance

to the adoption of the technology.

In most cases, an IP-based surveillance

system is more cost-eff ective than an

analog system. Furthermore, IP-enabled

equipment is expected to decrease in

price faster than analog equipment. Th e

previously referenced total cost of own-

ership analysis prepared by Axis Com-

munications concludes that IP-based

solutions of 40 cameras or more have a

lower cost to acquire, install, and oper-

ate than same-size analog-based solu-

tions. In fact, while 32-camera systems

are the break-even cost point between

the two systems, the analysis fi nds that

even 16- to 32-camera analog solutions

are only “slightly lower” in cost than

IP based systems.

Th e typical structured cabling im-

plementation topology for an IP-

based surveillance system is shown

on page 13. For maximum infrastruc-

ture fl exibility and to facilitate adds,

moves, and changes, it is recommend-

ed that a full crossconnect be pro-

vided in the TR. A side benefi t of IP-based

surveillance technology operating over

structured cabling is that cameras can

receive centralized backup power from

the server room, so they will continue to

operate in the event of a power failure.

IP in focus

Advanced video systems now deliv-

er the highest-levels of system perfor-

mance, image quality, fl exibility, and

intelligence; capabilities that can only be

realized with the implementation of IP-

based technology and a structured ca-

bling infrastructure.

Next month, I will have a companion

article discussing the use of structured

twisted-pair cabling infrastructure

to support broadband video and IPTV

applications.

The name Cooper Indus-

tries (www.cooperindustries.

com) may look familiar to

many professionals in the

structured cabling industry.

Th e company, which derives

most of its revenue from elec-

trical products, also off ers the Cooper B-Line brand of

products including cable tray and fi restopping prod-

ucts. Additionally, Cooper B-Line acquired GS Metals,

also a provider of cable tray, a little more than a year

ago. Cooper Industries’ footprint on the structured

cabling industry is not an insignifi cant one.

As a manufacturing business, Cooper Industries has

communications-infrastructure needs of its own and,

like its clientele, it seeks quality and value when making

purchasing decisions. Currently, Cooper is in the midst

of a communications-system upgrade that is marked by

the company’s geographical diversity, and geography has

played a part in several of the company’s decisions.

A global solution

Th e previous telephone system was a traditional dial

plan with handsets and standard voice messaging. Th e

central network interfaced among the companies divi-

sions in Wisconsin, Illinois, Missouri, Texas,

Georgia, North Carolina, South Caroli-

na, New York, and the United Kingdom.

Inter-offi ce calling required the dialing of the entire

long-distance number, so a critical need for the new

phone system was the ability for 8-digit dialing among

all its offi ces.

“Cooper wanted a phone system that would also enable

continued global business growth,” says Jeff Taft , strate-

gic partnership manager with CXtec (www.cxtec.com), a

provider of new and certifi ed pre-owned networking and

technology equipment. Taft adds, Cooper Industries has

been a CXtec customer for approximately six years, dur-

ing which time CXtec has provided pre-owned “equal-

2new” equipment as well as its own OEM products, in

addition to support services. In this situation, “Cooper

needed to leverage its global network and embrace the

age of the new telecommunications in-

frastructure,” he says.

CXtec recommended fl at-

tening, consolidating,

and simplifying Coo-

per’s phone system

so that core, neces-

sary services could

be available at all

of the company’s

locations. CXtec ad-

vised Cooper on a

single, Internet Pro-

tocol (IP)-based unifi ed

global communications system that comprises best-of-

breed technology with centralized management.

“When off ering a solution to any customer, it ulti-

mately boils down to the solid relationships we have with

our partners and their strong product off erings,” Taft

continues. “Our goal is to off er our customers the best

solution for their individual needs without being com-

mitted to only one or two vendor off erings.”

Ultimately, Cooper adopted a system that in-

Cooper Industries achieved effi cient communication across its

global sites thanks to the implementation of a unifi ed communi-

cations system.

Specifi cally, the suite of products includes Cisco’s CallManager

5.1 soft ware clustered system with Cisco IPCC and cold-spare

capability, and Netelligent Aware call recording.

The unifi ed big picture

Unifi ed communications as a technology is large and grow-

ing. In December, research fi rm Dell’Oro Group (www.delloro.

com) published a report stating the unifi ed communications

market surpassed $3 billion during the third quarter of 2008.

According to Dell’Oro, the $3 billion fi gure was driven in large

part by the market’s top two vendors, Cisco and Avaya (www.

avaya.com).

Th e report indicates that unifi ed communications is driv-

ing the enterprise-voice market from its hardware base, such

as private branch exchanges (PBXs), to soft ware.

“Functionality that has historically been confi ned to the core

PBX hardware is moving into soft ware applications that run on

data servers and phones,” commented Alan Weckel, a direc-

tor at Dell’Oro Group. “Previously unavailable features, such

as graphical corporate directories and Web browsing, are be-

coming telephony features. At the same time, functionality

that used to be tied to the phone at a person’s desk, such as

caller ID logs or voicemail indication, is becoming available in

cell phones and soft phones. More than ever before, the overall

enterprise telephony market, from the PBX switch to the desk-

top phone, is shift ing its emphasis toward soft ware.”

Another research and analyst fi rm, Gartner (www.gartner.

com), identifi ed unifi ed communications as one of the top 10

strategic technologies for 2009. (See sidebar, page 20.)

While the implementation of this unifi ed-communications

system is still rolling out across Coo-

per’s multiple sites, the company has al-

ready realized numerous benefi ts from

the project’s fi rst phase, including sev-

eral that Weckel mentioned in his com-

ments. With the Contact Center platform,

Cooper has been able to considerably im-

prove its call-center effi ciency, and the

Netelligent Aware call-recording sys-

tem has enabled employee coaching and

training, which has improved customer

service.

Reducing costs

Additionally, the 8-digit dial plan has

directly reduced the cost to make a call,

and the soft phones from Cisco have

allowed remote and mobile users to use

the global IP network as opposed to build-

ing cellular-phone expenses. Th e Cisco

Mobility feature has improved commu-

nication by having a single-reach number

that can reach an individual regardless of

that person’s location.

Th e increased communications effi cien-

cy required some Layer 1 infrastructure up-

grades, reports CXtec’s Tim Duff y. “Th at is

typically the case,” when a user transitions

from traditional phone service to an IP-based system. “But it

does vary by customer. Category 5e is the minimum cabling

requirement,” he says. “Some already have it installed, but in

most cases they do not—especially in older facilities.”

Th roughout the deployment of cabling systems and the uni-

fi ed-communications equipment, CXtec worked with Cooper

Industries to ensure the project ran smoothly. “We had an

on-site presence throughout,” says CXtec’s Duff y, “from

initial pre-sales interactions, we had a team that met with Coo-

“Category 5e is the

minimum cabling require-

ment. Some already have

was established and deployment was underway, the interac-

tion varied from weekly update calls to actually deploying the

technology on-site.”

Partnering for success

Because of Cooper’s dispersed locations, CXtec partnered with

another service-providing company. Depending on the loca-

tion being upgraded, either CXtec resources or those of its

partner were on site.

Overall, Cooper Industries’ implementation of a unifi ed

communications system has been successful because of the

ability of the technology vendors, CXtec, and Cooper to work

together. A collaboration of Netelligent’s expertise, Cisco’s

equipment and tools, and CXtec’s relationships with both re-

sulted in a smooth implementation. .

In October 2008, Gartner (www.gartner.com) present-

ed the Top 10 Strategic Technologies for 2009 at its

Symposium/ITxpo. Included with the likes of virtualization

and green IT was unifi ed communications. The analyst

fi rm defi nes a “strategic technology” as one with the

potential for signifi cant impact on the enterprise in the

next three years.

“Strategic technologies affect, run, grow, and transform

the business initiatives of an organization,” explained

David Cearley, vice president and distinguished analyst at

Gartner. “Companies should look at these opportunities

and evaluate where these technologies can add value to

their business services and solutions, as well as develop

a process for detecting and evaluating the business value

of new technologies as they enter the market.”

Specifi cally related to unifi ed communications, Gartner

said: “During the next fi ve years, the number of different

communications vendors with which a typical organiza-

tion works will be reduced by at least 50%. This change is

driven by increases in the capability of application serv-

ers, and the general shift of communications applications

to common off-the-shelf server and operating systems. As

this occurs, formerly distinct markets—each with distinct

vendors—converge, resulting in massive consolidation in

the communications industry. Organizations must build

careful, detailed plans for when each category of com-

munications function is replaced or converged, coupling

this step with the prior completion of appropriate adminis-

trative team convergence.” —P.M.

OUR BEST IDEAS COME FROM YOU

You asked for a 10 Gig cable that prevents alien crosstalk, and we responded. General Cable has developed a unique solution…finally, an Unshielded-Twisted Pair (UTP) 10 Gig cable that performs like a Shielded or Foiled-Twisted Pair (STP/FTP) cable. General Cable’s revolutionary Mosaic Twisted Pair™ design saves time and money over a shielded installation and provides industry-leading protection from outside noise sources, also known as alien crosstalk (PSANEXT).

Flex-Separator TM

optimizes internal pair geometry to yield superior electrical performance while maintaining cable flexibility. This unique miniaturized cross- web stabilizes each pair and creates an overall smaller, round cable profile.

The Mosaic CrossblockTM

is made up of individual metallic blocks separated by an insulating layer. Since there is no metal-to-metal contact, there is no path for current to flow longitudi-nally, and thus, no need for grounding. Each block contains eddy currents that act together to cancel the electric field outside the cable.

Multimode opti-

cal fi bers have always off ered

users the most cost-eff ective

choice to achieve the benefi ts of fi ber-optic transmission

in premises applications. Th e simple reason is that the

electronics are less expensive than those used to power

singlemode fi bers. While TR-42, the User Premises Tele-

communications Cabling Requirements Engineering

Committee, has recognized both mul-

timode and singlemode optical fi ber

for private-network structured cabling,

this was because a combined system

has always provided the best value for

the end user who might need single-

mode fi ber to support long distances or

very high data rates.

Th e good news is that the newest

generations of multimode fi bers can

support the same high data rates as sin-

glemode, including 40 and 100 Gbits/sec,

while retaining the cost savings associ-

ated with multimode fi bers.

TR-42 initially recognized 62.5-μm multimode fi ber in

ANSI/TIA-568, Th e Commercial Building Cabling Stan-

dard. As newer applications and optical sources came

along, the higher-bandwidth capabilities of 50-μm fi -

ber became recognized as well. As transmission speeds

increased, the market shift ed from 62.5-μm to 50-μm

fi ber and, more recently, to 50-μm laser-optimized fi ber

(OM3). Th is trend will be accelerated with the advent of

40/100-Gigabit Ethernet (GbE) because there is no OM1

or OM2 objective at these next-generation speeds.

The next speed generations

Th e current objectives for both 40 and 100 GbE are to

cover a distance of at least 100 meters on

OM3 fi ber. Th e 100-meter value will al-

low for extremely low-cost transceivers,

but is well short of the 300-meter dis-

tance allowed by TR-42 in the TIA-942

data center standard; and no one seems

excited about having to use singlemode

electronics and singlemode fi ber for

every link in their network that reached

farther than 100 meters.

In a survey presented at the Institute

of Electrical and Electronics Engineers

(IEEE; www.ieee.org) 802.3 meeting in

July 2008, 20 diverse end users were asked to consider

three options. (Note that OM4 is a higher-bandwidth

multimode fi ber that will be discussed in greater detail

later in this article). Th e three options were:

A) OM3 to 100 meters (requires one optical module);

B) OM3 to 150 or 200 meters; OM4 to 250 meters

(requires one optical module);

C) OM3 to 100 meters; OM3 to 150 or 200 meters; OM4

to 250 meters (requires two optical modules).

Th e survey results were overwhelmingly (16 or 20) in

favor of Option B: OM3 to 150 or 200 meters and OM4

to 250 meters. A minority (4 of 20) favored Option C:

OM3 to 100 meters. All survey participants believed the

100-meter transmission length limit suggested by 802.3

would increase the cost of data centers at 40/100-Gbit/sec

speeds by forcing them to use a more expensive single-

mode system to meet their link-length requirements.

Multimode fi bersrise to the challenge

An update on the current state of optical fiber

in standards, including the definition of OM4.

extended reach, and working on extending

the multimode distance from the current “at

least 100 meters on OM3” to somewhere be-

tween 150 and 250 meters. Technical feasi-

bility for these extended distances has been

shown. What remains is to identify the dis-

tance and technical path that will provide the

best, lowest-cost solution. Th e goal is to en-

sure that multimode fi ber customers contin-

ue to get the best bang for their buck.

One possible path to achieve the extended

distance would be through the use of a high-

er-bandwidth fi ber. Unfortunately, the transceiver specifi ca-

tions that are currently proposed for the 40/100-GbE standards

are such that a higher-bandwidth fi ber, on its own, doesn’t pro-

vide much benefi t. Th e sources have such broad spectral widths

that the eff ects of higher bandwidth may only extend the dis-

tance by a few percent. But a higher-bandwidth fi ber, combined

with tighter transceiver specifi cations or a chip added to the

host board, could support link lengths of at least 250 meters

on multimode fi ber.

Developers of standards using the Fibre Channel (FC) pro-

tocol also have started talking about next-generation speeds.

Th is set of standards increases speeds by a factor of 2 with each

generation. Standards are currently in place for 8-Gbit FC, with

discussions around creating a 16-Gbit standard on the hori-

zon. In a Fibre Channel meeting last year, participants agreed

that a multimode fi ber with signifi cantly higher bandwidth

should be developed/characterized to support 16-Gbit/sec

serial transmission over 150 meters.

trotechnical Commission; www.iec.ch). Both the IEEE 802.3

(Ethernet) and Fibre Channel application standards groups

have expressed interest in a higher-data-rate multimode fi ber

above and beyond the performance currently off ered by OM3

fi ber. Th is has prompted the ISO/IEC premises wiring cable

committee to request the development of a new high-data-rate

multimode fi ber standard.

OM3 and OM4 are referred to as “laser-optimized” multi-

mode fi bers because they are specifi cally designed for use with

high-performance, low-cost vertical-cavity surface-emitting

lasers (VCSELs). Careful processing to precisely control the

fi ber’s refractive index profi le is paramount to minimize

modal dispersion—or, diff erential mode delay (DMD).

By limiting DMD, all modes (light paths) in the fi ber arrive

at the transceiver at the same time, minimizing pulse spread-

ing and thus maximizing bandwidth. Bandwidth is ensured by

thorough DMD testing aft er the fi ber is manufactured. Th us,

these higher-bandwidth fi bers provide a combination of lon-

ger reach and lower system implementation cost for current

(e.g., 10-Gbit/sec) and more importantly, future higher-data-

rate multimode fi ber systems.

Standardized in 2002, OM3 fi ber has a minimum eff ective

modal bandwidth (EMB) of 2,000 Mhz∙km at 850 nm using

VCSEL transceivers. Th is is suffi cient bandwidth to operate a

10-Gbit/sec Ethernet system up to 300 meters. An OM4 fi ber

is expected to specify a minimum EMB of 4,700 MHz∙km at

850 nm—more than twice the bandwidth of OM3.

OM3 fi bers are backward-compatible and can support leg-

acy applications that use LED transmitters operating at either

850 or 1,300 nm. Th ere is a general consensus among the fi ber

manufacturers that OM4 will also be backward-compatible;

however, the standard is still in the early stages of development

and the exact specifi cations have not been fi nalized.

TIA standards committee TR-42.12, Optical Fibers and

Cables, is developing the specifi cation to be named TIA/EIA-

492AAAD “Detail specifi cation for OM4 850-nm laser-opti-

mized, 50-μm core diameter/125-μm cladding diameter class

1a graded-index multimode optical fi bers.” Th is standard is

scheduled to be ratifi ed in mid-2009. In parallel, IEC SC 86A

Working Group 1 initiated work on the OM4 fi ber standard-

ization in April 2008. Th e A1 MMF standard 60793-20-10 will

be revised to include a higher grade A1a.3 (OM4) fi ber.

Laser-optimized 50-μm fi bers (OM3 and the future OM4)

will support 10-Gbit/sec transmission over 300 to 550 meters.

For 40- and 100-Gbit/sec transmission, they will support at

least 100 meters, but eff orts are underway to increase that dis-

tance to 150 to 250 meters. Th is longer distance would cover the

majority of LAN and data center link-length requirements.

By enabling signifi cantly lower-cost transceivers, multimode

fi ber systems continue to be the low-cost, future-ready solution

for premises networks of yesterday, today, and tomorrow.

802.11 network overview

Clients

www.cablinginstall.com wireless


In late September of last

year, the IEEE (www.ieee.

org) approved for publica-

tion the 802.11y wireless

standard, enabling high-powered Wi-Fi equipment to

operate in and “cooperative use” of the mostly vacant

3650 to 3700 MHz band. In essence, the amendment

to the 802.11-2007 standard, in conjunction with the

FCC’s (www.fcc.gov) 3650 MHz Order established in

2005, allows for increased wireless operation for more

users at a much higher power than via traditional Wi-Fi

equipment—up to 3 miles or more—and, according to

the FCC will “create a spectrum environment that will

encourage multiple entrants and stimulate the expan-

sion of broadband service,” especially in rural areas.

Th e Wi-Fi Alliance (www.wi-fi .org), a non-profi t in-

dustry association of more than 300 member companies

devoted to promoting the growth of WLANs, recently

published a discussion paper on the 802.11y standard, “A

New Regulatory and Technical Environment for Wire-

less Broadband.” In its report,

the Alliance notes that the key

intentions of the FCC order in-

clude “to lower the cost of entry

and compliance while allowing

market forces to derive maxi-

mum value from the available

spectrum through shared use.”

Th e Order requires robust co-

existence capabilities, and the

Alliance says that “Wi-Fi technology is especially well

suited to meet the requirements for avoiding interfer-

ence…Because the contention-based protocol used by

Wi-Fi technology senses and responds to a broad range

of potential technologies, 100% of the 3650 MHz band is

available to networks using the 802.11y protocol.”

Th e 3650 MHz band has been largely vacant due to

the range limitations of radio waves and intentional fre-

quency spacing to avoid interference, but the Alliance

deployment of [the Wi-Fi] model in the 3650 MHz band can

and should lead to a much broader allocation of spectrum for

lightly licensed networks utilizing a contention-based pro-

tocol mechanism—eventually including most of the known

unused or underused radio spectrum.”

Light licensing means that licensees pay a small fee for a

nationwide, non-exclusive license, and then pay an additional

nominal fee for each deployed high-powered base station.

Potential installations include industrial automation and

control, campus and enterprise networks, and public safety

and security networks. In one scenario of a potential 802.11y

installation, a fi re station locates an enabling station (see

description below) on its communications tower, and uses

dependent stations on each fi re truck and

laptop. Th e incident commander controls

the enabling station using a Public Safety

band radio.

Wi-Fi Alliance discussion paper excerpt

Th rough the courtesy of the Alliance, the fol-

lowing excerpts from their white paper de-

scribe the major elements and operation

overview of an 802.11y network:• Enabling stations. An enabling station is a high-powered

fi xed station with authority to control when and how a

dependent station can operate. An enabling station commu-

nicates an initial enabling signal to its dependents over the

air. Th e enabling station may then direct supporting enable-

ment messages to be exchanged over the air, over another

dependent station, or by mechanisms that rely on transport

via higher layers. As with all high-powered stations, GPS co-

ordinates and altitude information of enabling stations are

registered in a public database to enable stations experienc-

ing interference to locate interfering stations and seek inter-

ference mitigation. Enabling stations must include location

information in every beacon. • Dependent stations. Dependent stations are devices in the

network that are not registered, but instead receive authori-

zation to transmit from a registered enabling station over the

air. Failure to receive the enabling beacon at regular, defi ned

intervals requires a dependent station to suspend transmis-

sion until it is re-enabled. A dependent station may be fi xed

or mobile. • Regulatory class information. Each device in a network

must be able to operate within regulatory requirements of

any channel available to it. Prior to 802.11y, channel switch-

ing only occurred within a particular band, where only trans-

mit power limits may have changed. Future implementations

will be able to move outside of the original band, comply-

ing with the regulatory requirements specifi ed by the regula-

tory class octet in every beacon.

Together, these new elements support three signifi cant new

mechanisms defi ned in 802.11y: • Dynamic Station Enablement (DSE). [Th is is] the process

by which an enabling station grants permission and dic-

tates operational procedures to dependent stations. Th e light-

ly-licensed structure of the FCC regulations for 3650 MHz

calls for the creation of procedures to govern the use of the

band and treatment of violations. DSE supports the light-

ly-licensed regulatory model by empowering the network

operator to ensure appropriate operation of base stations

and the dependent stations they enable. Beyond addressing

the regulatory requirements for the 3650 MHz Order, DSE

off ers the promise of other channel management and coor-

dination benefi ts.1 For example, since the enabling station

is not required to serve as the access point for each of its de-

pendent stations, DSE can reduce the likelihood of a depen-

dent station contributing to radio interference by allowing

the dependent station to complete the enablement process via

a geographically closer access point and ultimately through

a channel other than the air (e.g., the Internet).1

• Contention-based protocol incorporating regulatory class

information. 802.11y devices can sense both 802.11 and non-

802.11 devices and identify available spectrum as small as

5MHz. 802.11y access point beacons identify the country

and the regulatory domain for their physical location. By

incorporating both channel use and regulatory class infor-

mation, 802.11y devices can identify available channels and

adjust operating parameters to the laws of the country in

which the access point resides. • Extended Channel Switch Announcement (ECSA). A meth-

odology to coordinate a move from one channel to anoth-

er with less contention or to change channel bandwidth.1

Specifi cally, an enabling station can identify the channel

with the least aggregate interference to all of the stations

that are connected to it on a completely dynamic basis. Th is

capability ensures the best signal-to-noise ratio and lowest

power levels possible. ECSA also incorporates regulatory

class information—if a channel switch moves the network

to a new regulatory domain, the station shift s to the approved

frequencies and channels for the new domain. ECSA orig-

inates in 802.11y, and is now being applied retroactively to

802.11n and the other proposed concepts across 802.11.

The improved quality of service (QoS) made pos-

sible by higher power levels will make Wi-Fi tech-

nology more attractive for intensive applications like

Voice over Internet Protocol (VoIP).

Network operation overview

Th e fi rst requirement for establishing an IEEE 802.11y network

is determining if the area to be covered is in an exclusion zone.

If it is outside of the protected regions, the network operator

must fi le for a license, pay a small fee, and regis-

ter the location of the enabling station in a public

database. Dependent stations, fi xed and mobile,

may then be added to the network based on their

ability to receive and decode the enabling beacon.

Once enabled, each dependent station continually

tests its ability to receive and decode an enabling

beacon. Failing this test, the dependent station at-

tempts to reacquire the beacon, with a fi nite number of attempts

before ceasing trying for a predetermined amount of time.

Th is requirement prevents congestion caused by stations that

may be truly out of range of an enabling beacon. Enabling

stations continually test for interference. If interference is de-

tected, the enabling station must silence the network and

search for a clear channel. When a new channel is identifi ed,

ECSA directs all of the devices in the network to move to the

new channel, which may include a change in regulatory class,

as specifi ed by the regulatory class octet.

Potential installations include industrial automa-

tion and control, campus and enterprise net-

works, and public safety and security networks.

Low-cost chipsets and the capability to eff ectively man-

age interference through contention-based protocols make

Wi-Fi technology an excellent fi t for applications in this spec-

trum. Th e improved quality of service (QoS) made possible by

higher power levels will make Wi-Fi technology more

attractive for intensive applications like Voice over Internet

Protocol (VoIP).

PERFORMANCE WITHOUT COMPROMISE

When Miami, FL-based Concord

Electric Contractors was tasked

to upgrade the computer and media in-

frastructure for the Immaculata-LaSalle

High School, the limited room for cable

runs presented an installation challenge.

Concord found the solution in Isotec’s

(www.isotec.com) new SIMTRA Ferrite-

Barrier power cables, which are designed

to be both a space and time saver.

“Th e Immaculata-LaSalle installa-

tion posed signifi cant design issues be-

cause of the lack of space to run wires,”

says David Linenfelser, electrical su-

pervisor at Concord Electric Contrac-

tors. “Th e Isotec SIMTRA power cables

became the only solution for the instal-

lation because the unique design of the

SIMTRA wire allows for multi-format

media and low-voltage cabling to co-ex-

ist in the same conduit as the 120 volt AC

power cable without interference, while

only having to run one cable.”

SIMTRA cables conform with NEC

specifi cation sections 725.136, 760.136,

770.133, 800.133, 800.179, 820.133 and

830.133, and are designed to elimi-

nate transients and interference. Each

conductor of the power cable is sur-

rounded by a proprietary ferrite bar-

rier that provides shielding within the

cable itself, thereby attenuating surges and

minimizing interference that can corrupt

the signal in adjacent low-voltage cables.

Th e Immaculata-LaSalle project re-

quired several diff erent types of cable

to be run to each classroom. For in-

stance, each classroom has cables run-

ning to the teacher’s desk that provide

interconnections for the video projec-

tor, DVD, audio amplifi er and comput-

er networking, in addition to power for

each student desk.

Barrier cable technology allows forpower, low-voltage in one conduit

Survey: wireless is hottest thing on campus

➤

Proprietary design of Isotec Inc.’s SIMTRA wire allows for

multi-format media and low-voltage cabling to co-exist

without interference in the same conduit as a 120 volt AC

power cable.

Power outlets for each stu-

dent computer were posi-

tioned next to each desk, but

there was not space available

for multiple conduit runs. By

using SIMTRA power ca-

bles, however, Concord Elec-

tric Contractors was able to

pull the projector wiring, TV

cable, speaker wire, data

cable, and AC power all in

one conduit into the room,

breaking out Category 5 Eth-

ernet cable and AC for the

individual student stations.

Also, since the cable could be

run through the small space

in the fl oor, installers were

able to eliminate the extra

step of supporting the cables every four

feet— required when running low-volt-

age cable through ceilings.

“A big benefi t of the SIMTRA cable is

time savings on a job and streamlining

the installation to meet code,” explains

Linenfelser. “Also, whenever you go

through a classroom wall, the building

codes consider it a fi rewall, and that

requires a whole new set of rules. What’s

benefi cial with SIMTRA is that we actu-

ally run one large conduit from the class-

rooms to the main room where the high

voltage and low voltage all converge,

eliminating the need for multiple pene-

trations of the fi rewalls. [For] Immacu-

lata-LaSalle, SIMTRA cable actually

made this installation possible.”

Arecent survey indicates that near-

ly three out of four colleges and

universities plan to expand their wire-

less networks over the next two years.

Th at is one of the key fi ndings in the lat-

est member survey by ACUTA (www

acuta.org), the Association for Informa-

tion Communications Technology Pro-

fessionals in Higher Education, which

surveyed members at its 2008 Fall Sem-

inar in Boston.

Th e survey asked members to iden-

tify the most signifi cant change in their

cabling and wiring infrastructure over

the last several years. Sixty percent said

that change was deployment of wireless

networks, compared with 13% pointing

to installation of fi ber-optic cable and

another 13% citing rewiring projects for

technology upgrades.

Two out of three survey respon-

dents said it was the demand for

“connectivity anywhere” that drove their

key networking change, while 40%

ARLINGTON, VA—The Telecommunications Industry Association

(www.tiaonline.org) has updated the 568-C.3 Optical Fiber

Cabling Components standard, which specifi es cable and

component transmission performance requirements for premises

optical-fi ber cabling. Signifi cant technical changes include:

incorporating the performance specifi cations for 850nm laser-

optimized 50/125-μm multimode cables previously found in

ASNI/TIA/EIA-568-B.3-1; specifi cations for indoor-outdoor cable,

including minimum bend radius and maximum pulling tensions;

and array connector specifi cations. Copies of the document are

available at: www.global.ihs.com

STERLING, VA— As the data center continues to evolve and

mature, business-oriented goals are driving the adoption of

Ethernet as the single network technology, according to a new

Current Analysis Advisory Report, “One Love, One Data Center,

One Network.” According to the report’s

author, Steven Schuchart, Current Analysis principal analyst/

data center, “For there to be truly agile, cost optimized, and

effi cient data centers, the network must be transitioned to a

single technology. That technology is Ethernet. There is signifi cant

opportunity to break the old networking paradigms and advocate

one network technology for the data center.” In the report,

Schuchart looks at why Ethernet is the natural choice for a single

network, including its wide deployment, and the willingness of

Ethernet’s vendors to work together to ensure that the technology

is compatible, regardless of brand or origin. For a complimentary

LITTLE NECK, NY—In February, Leviton (www.leviton.com) will

open a new 450,000-square-foot distribution center in Lebanon,

TN. The fully automated facility will serve as one of the company’s

two state-of-the-art domestic warehouse and distribution

hubs. The Tennessee center will service customers east of the

Mississippi River, and feature the company’s commercial-grade

occupancy sensors, light switches, outlets, and commercial

networking devices.

ANAHEIM, CA—To help facilities managers and engineers

address power issues, Electrorack (www.electrorack.com)

has designed a downloadable Power Distribution Catalog that

highlights a wide selection of Power Distribution Units (PDUs),

power consumption monitoring solutions, and mounting methods.

Electrorack’s PDU options are designed to give facilities managers

the ability to closely monitor current draw, and determine where

and how to distribute power via a selection of current, voltage,

mounting options and plug types. Voltage ranges are 120, 208,

208/3-Phase), and amperage ranges are 15, 20, 30, 50 and 60.

said the evolution of communication

styles was a major factor. Meeting grow-

ing capacity needs and migration to Voice

over IP and Unifi ed Communications

were other drivers cited, at 33% and 23%

respectively.

Th e single greatest benefi t of their

change, said responding ACUTA mem-

bers, was network access anywhere and

anytime (42%); user convenience (23%);

network effi ciencies (17%); and greater

bandwidth (10%).

On the downside, 56% of respondents

said the cost of their change was their

greatest challenge, while another 21%

said locating and installing the many

wireless access points needed for cover-

age was their biggest hurdle.

Asked about the next signifi cant step

in their campus networking, 71% said

expansion of their wireless network—or

installation of one if they haven’t done so

already—is in their plans. Another 19%

pointed to additional rewiring projects

as information communications tech-

nology evolves. As far as the timeframe

for their next big steps, 73% of respon-

dents expect to take those steps within

one year.

Finally, asked to identify how their

ongoing changes aff ect both them and

their departments, respondents said

the highest impact issues are ever-tight-

ening budgets, a greater need for long-

range planning, the need to learn new

technology skills, the fact that growing

campuses mean more responsibility for

their departments, and the challenge of

fi nding employees with the right mix of

skills.

“The fact that wireless network-

ing is the biggest change for our mem-

bers and their schools isn’t surprising in

itself,” says Jeri Semer, executive director

of ACUTA. “But this survey shows the

impact that wireless networks, as well as

other forms of technology evolution, are

having on information communications

technology departments.”

Semer adds, “While wireless net-

works do make communications and

computing far more convenient on cam-

puses, they do have their challenges in

terms of cost and management. Th e

same is true for other advancing tech-

nologies as well.”

High-speed networking alliances plan to merge

The Ethernet Alliance (www.

ethernetalliance.org) and the Road

to 100G Alliance plan to transition as

one organization under the Ethernet

Alliance. Both industry organizations

promote the advancement of high-per-

formance Ethernet networking.

Th e non-profi t Road to 100G Alliance

seeks to provide seamless interopera-

bility among the disparate, standards-

based components required to build

high-capacity network elements. Th e

Ethernet Alliance seeks to promote

industry awareness, acceptance, and

advancement of technology and prod-

ucts based on existing and emerging

IEEE 802 Ethernet standards.

“Th e Road to 100G Alliance has met

and exceeded its expectations in terms

of exposing the challenges of develop-

ing 100G platforms,” says Bill Weisinger,

chairman of the Road to 100G Alliance.

“With the challenges well understood, it

is the right time for us to join with the

Ethernet Alliance and fulfi ll the balance

of our goal—to establish a comprehen-

sive ecosystem of suppliers and users

to accelerate the adoption and ongoing

development of high-performance net-

working solutions.”

Brad Booth, chairman of the board

for the Ethernet Alliance, notes, “Th e

demand for bandwidth is growing in ev-

ery market segment—from consumer to

enterprise to service and content provid-

ers. Th e Ethernet Alliance praises the

Road to 100G Alliance and its members

on highlighting the challenges of 100G

and is honored they believe the Ether-

net Alliance is the organization to fur-

ther their goal.”

Booth adds, “Given the alignment of

our visions and strategies, the combina-

tion of our two organizations will greatly

advance the development of the high-

speed Ethernet ecosystem, benefi ting

customers worldwide.”

In November 2007, the IEEE 802.3

working group authorized the forma-

tion of the IEEE P802.3ba task force to

begin work on a draft standard for 40

Gigabit and 100 Gigabit Ethernet. Late

last fall, the task force completed review

of the fi rst draft of IEEE P802.3ba, which

keeps the task force on track for standard

ratifi cation by mid-2010.

The Ethernet Alliance has also

announced an internship program as

part of its Ethernet Alliance Univer-

sity Program (EAUP). Th e program

promotes internship opportunities by

connecting corporate members with cur-

rently enrolled student of EAUP aca-

demic members. Th e Alliance accepts

student resumes and makes them avail-

able to corporate members via its online

database.

“As someone who graduated from a co-

operative engineering program, I know

that today’s university students will have

a direct infl uence on helping shape Eth-

ernet technologies in the years to come,”

says Booth.
