Brief

To get idea of fibre to home, we first need to understand basic difference between communication over conventional copper, wireless mediums and next of fibre. 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 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 car running at high speed!Till now there has been no way out to 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 main part of this post – fibre. In case of fibre, communication is done using light which travels in whole fibre via a simple Physics rule called total internal reflection. Principle is quite simple, but it makes communication very effective as fibre 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 fibre as compared to copper. This makes fibre a very good “Physical” medium for carrying high bandwidth.
