How FTTH Broadband Works?
Stop and think how your Internet usage has evolved during the last few
years. If you’re like most people, you will do, and looking forward to more
online interaction, such as increasing rich media and upload and download
images and video.
More large files are moving across the cyberspace network these days, and
experts expect that trend will only increase. In January 2008, the study
by the Discovery Institute estimates new technologies will drive Internet
traffic up by 50 times its current rate within the next 10 years.
The pressure for better connectivity is one of the main reasons providers
and users to view its fiber to the home broadband connections as a
potential solution.
FTTH broadband connections, refer to optical fiber cable connection for
individual residences. Such optical based system can provide large amounts
of digital information, telephone, video, data, and so on, more efficiently
than traditional copper coaxial cable for about the same price. FTTH
premises depend on both active and passive optical networks to function.
FTTH network cables connection is a reality of more than 1 million
consumers in the United States, and more than 6 million Japanese and 10
million global to enjoy its benefits, broadband property according to the
magazine. Many people think that the FTTH technology standard to
predict network connection can solve traffic congestion.
More than 10 million homes worldwide already have fiber to the home
broadband connections because the technology holds many advantages
over current technologies.
What are the advantages to FTTH broadband connections?
A key advantage to FTTH – also called FTTP, for “fiber to the premises”
broadband – is that it provides for far faster connection speeds and
carrying capacity than twisted pair conductors, DSL or coaxial cable.
Experts at the FTTH Council say fiber-to-the-home connections are the
only technology with enough bandwidth to handle projected consumer
demands during the next decade reliably and cost effectively. The
technology is already, affordable, as businesses around the world are
demonstrating by getting into the business as they speculate on consumer
demand.
Fiber has a virtually unlimited bandwidth coupled with a long reach, making
it “future safe,” or a standard medium that will be in place for a long time
to come.
However, greatly improving the bandwidth cost and current technology.
According to the FTTH Council, cable companies spent about $84 billion to
line family ten years ago, but it costs less in today’s dollars line those
houses with FTTH technology.
FTTH will be able to handle even the future Internet use some experts see
the future. Technologies such as 3D holographic high definition television
and games will one day become daily necessities of families all over the
world. FTTH will be able to handle estimated 30-gigabyte-per-second
needs of such equipment.
Active and Passive Optical Networks
There are two important types of systems that make FTTH broadband
connections possible. These are active optical networks and passive optical
networks. Each offers ways to separate data and route it to the proper
place, and each has advantages and disadvantages as compared to the
other.
An active optical system uses electrically powered switching equipment,
such as a router or a switch aggregator, to manage signal distribution and
direct signals to specific customers. This switch opens and closes in
various ways to direct the incoming and outgoing signals to the proper
place. In such a system, a customer may have a dedicated fiber running to
his or her house.
A passive optical network, on the other hand, does not include electrically
powered switching equipment and instead uses optical splitters to separate
and collect optical signals as they move through the network. A passive
optical network shares fiber optic strands for portions of the network.
Powered equipment is required only at the source and receiving ends of the
signal.
Active and Passive Optical Networks of the advantages and
disadvantages
Passive optical networks, or PONs, have some distinct advantages. They’re
efficient, in that each fiber optic strand can serve up to 32 users. PONs
have a low building cost relative to active optical networks along with lower
maintenance costs. Because there are few moving or electrical parts,
there’s simply less that can go wrong in a PON.
Passive optical networks also have some disadvantages. They have less
range than an active optical network, meaning subscribers must be
geographically closer to the central source of the data. PONs also make it
difficult to isolate a failure when they occur. Also, because the bandwidth
in a PON is not dedicated to individual subscribers, data transmission
speed may slow down during peak usage times in an effect known as latency.
Latency quickly degrades services such as audio and video, which need a
smooth rate to maintain quality.
Active optical networks offer certain advantages, as well. Their reliance on
Ethernet technology makes interoperability among vendors easy.
Subscribers can select hardware that delivers an appropriate data
transmission rate and scale up as their needs increase without having to
restructure the network.
Active optical networks, however, also have their disadvantages. They
require at least one switch aggregator for every 48 subscribers. Because
it requires power, an active optical network inherently is less reliable than
a passive optical network.
