Fiber to the Office

Key Terms

• PON - Passive Optical Network - (Carrier) Between Central Office (CO), or substation, and the premises in FTTx.

Campus MDF

• POL - Passive Optical Local Area Network

- (Enterprise) Between the data center / equipment room and the user*.

PON / POL are a point-to-multipoint network architecture in which unpowered

optical splitters are used to enable a single optical fiber to serve multiple

premises / users

GPON (Gigabit PON) is an evolution of the BPON

standard - based on the ITU standard (ITU-G.984)

Asymmetrical bandwidth 2.4Gbs / 1.25Gbs

Fundamentally GPON is the common demoninator for PON and POL

Overarching technology

A thought to begin with…

“If you always do what you

always did, you will always

get what you always got.”

Keeping pace with the many changes in IT

Change has been to main driver for most enterprises in the last decade

Bandwidth requirements have increased by order of magnitude

Numbers and type of devices connected has also jumped dramatically

Traffic patterns have shifted to more centralised and cloud based

Ironically It’s all happened in an economic environment

that gives IT much less to spend.

And yet costly work groups switch based architecture are built the same way

Main Factors for Change

• Rethinking of the physical infrastructure / abandoning old assumptions

• Re-evaluation of the way the LAN architecture is deployed

• Re-consideration of processes and vendors

• Alignment of IT to the business agenda

Gradually an increasing number of enterprises are abandoning some of

the assumption they used to make and start looking at alternatives

IT architectures are changing and therefore the network architecture has to adapt with it.

Evolution of network technologies…departmental and distributed services vs. to centralised

resources into the Data Center or even into the cloud

Emerging trend where intelligence and functionality features are centralised back to a single

location or aggregation

Think of Wireless LAN…. Where a relative number of non-intelligent access points feed-up

into centralised controllers that provide all the intelligence and functionality for the whole wireless

LAN

Now think of GPON as the other disruptive technology where again we are using passive

technology down to the desktop and then centralise a lot of the intelligence at the aggregation

or core layer within that architecture.

Game changer & Disruptive Technology

Taking unnecessary intelligence and functionality away from the edge

in order to create a more efficient architecture

POL Market Drivers

• Functionality

– Understand business requirements

– Rethink and revaluate old assumptions

• Financial

– Reconsider procurement

– What business problem does it solve?

• Operational

– Improve efficiency / increase security / reduce OPEX

GPON Evolution

The success of the OSP system has created an opportunity to bring

the same system design into the enterprise LAN

Splitter Technology

• Splitters are passive components representing an important role in Passive

Optical Networks

• Two types used:

• Fused Biconilcal Taper (FBT) – old technology

• Planar Lightwave Circuit (PLC) – latest technology

• Multiple input (M) and multiple output (N) – 1x2 / 1x8 / 1x16 / 1x32 / 2x32

• PLC Splitter, based on silica optical waveguide technology and precision

aligning process

• Theoretical loss for a 1x32 is 15db – good PLC splitter provide <16.5db

Optical LAN Link Budgets

May 15, 2014 19

• The maximum PON distance is limited primarily by optical attenuation. Contributors are fiber loss attenuation and PON splitter attenuation.

• Optical LAN loss budges must be between 8dB and 28dB; meaning smaller split ratios may require an inline attenuator to insert more loss.

PON

Splitter

Fiber loss per km

is 0.35 dB (1260 - 1360 nm)

Every time the signal is split two ways, half the power goes one way and half goes the other. So each direction gets half the power, or the signal is reduced by

10log(0.5)=3 dB

Practical loss is 3.5 dB nominal, so every two-way split costs about 10 km distance @ 1310 nm

Standard Bodies Update

In February 2009, the Telecommunications Industry Association TR-42

Engineering Committee published TIA-568-C.1, which was the first revision to

recognize duplex single-mode fiber for use in the horizontal.

On August 14, 2012, TR-42 issued an addendum to the TIA-568-C.0 Generic

Telecommunications Cabling for Customer Premises standard that adds POL

technology standards as supported single-mode fiber applications for the LAN.

Note: POL added to 13th Edition of TDMM – Chapter 5 Horizontal Cabling

Founded to advocate the global adoption of passive

optical networks in the LAN marketplace
