Brief To get idea of fiber to home, we first need to understand basic difference
between communication over conventional copper, wireless mediums and
next fiber.
The biggest problem in using copper in communication is “noise”. Copper
pairs get noisy over distance, apart from getting too much effect of
interference from the nearby environment.
Now to carry more bandwidth, one needs to use really high frequencies (like
we do in various types of DSL), and high frequencies are affected by noise
even more. Imagine noise as roadblock interrupting traffic, and high
frequency as a car running at high speed!
Till now there has been no way out of the noise problem of copper. A lot of
research work is still going on, but till now all what we see is multiple
bonding of pairs for increasing speeds.
Next, if you look at wireless communication – as I explained in my last post
due to limited spectrum, overall capacity is very much limited, and one can’t
provide high speed broadband for very low rates to everyone. That is what
makes 3G, EVDO and other stuff expensive.
Now coming on the main part of this post – fiber. In case of fiber, communication
is done using light which travels in whole fiber via a simple Physics rule
called total internal reflection. Principle is quite simple, but it makes
communication very effective as fiber is NOT prone to interference by any
external element like other wires, apart from that loss of signal per Km is way
too less in fiber as compared to copper. This makes fiber a very good
“Physical” medium for carrying high bandwidth
