FTTH stands for Fiber To The Home. It
is the best idea so far for high-speed networking, high speed data transfer,
digital television and telephone service to residences using Fiber Optic cables
(FOC). Although we think, the speed that we are getting today is very high but
in reality it is not.
Telecommunications companies are trying
to develop a technology to support 100+ Mbps bandwidth per home. They view
fiber optic cabling, Fiber To The Home, as the best technology for achieving
these standards. It will replace copper from the Telecommunication system.
WORKING OF FTTH
The basic concept or aim of the FTTH
technology is to provide very high speed service. This is done by using Optical
Fiber Cable. The bandwidth of these cables is very high. So a large amount of
data can be transferred at any point of time. If we observe carefully the cause
of less speed is copper wire, junctions at MDF, pillars connection etc. In the
case of FTTH all these problems are solved. Here, instead of copper wire we use
Optical Fiber Cable which has extremely high bandwidth, thus provides a very
high speed. In FTTH there in nothing called as MDF. We have Optical Line
Terminal (OLT). Switch Room, Broad Band server, IPTV server, etc. are directly
connected to the OLT with the help of Optical Fiber Cable. This assures a very
high speed of DATA transfer. After that we send two wires to the optical
splitter, these fibers are being send via two different routes. The reason of
two different routes is to overcome the situation when there is any damage in
the wire of one route. At a given point of time only one of these wires is
sending and receiving the data. As discussed earlier here we have different
bandwidth for receiving and transmitting data. The next level is optical
splitter. The data when reached the splitter it gets divided into many parts,
i.e. depending upon the splitter. From splitter the splitter the data is send
to the ONT (Optical Network Terminal). From ONT (Optical Network Terminal) the
data is transmitted to the respective homes or destination. The last part of
the connection can be undergrounded or hanging wire type. One of the most
important advantage of FTTH is that if any person will change some wires in
splitter there will not be any problem in the billing or facilities. Let’s take
an example of the FTTH, if the speed of data from OLT is 24Mbps and it is
supplied to the 1:24 splitter then each subscriber or ONT will get the speed of
1 Mbps.
ADVANTAGES OF FTTH:
It is very cheap
technology as Fiber is manufactured from the Silica which is obtained from Sea
Sand.
It provides far
faster connection speeds and carrying capacity than previous technologies.
The bandwidth in
FTTH technology is so high that a single fiber pair of fiber can carry more
than 25, 00,000 (25 lakhs/2.5 million) phone calls at the same time.
Experts
of the FTTH council consider FTTH as the only technology which can handle the projected
number and demands of consumers during the next decay.
FTTH
will be able to handle the futuristic Internet. Technologies such as 3D
holographic high definition television and games will someday be everyday items
in households around the world.
FTTH
technology will be able to handle the need of estimated 30-gigabyte-per-second for
many advanced equipment’s. We can't imagine Current technologies come even close
to FTTH ever.
Limitations of FTTH:
Initial
laying cost is very high.
