Fiber Optics

Fiber Optic Cable
Optical Fiber cables - often referred to as Fiber optic cables - are new types of cables which can carry commutations data, very quickly i.e. broadband, phone etc. Fiber optic cables are very thin strands of glass - about the thickness of a human hair. When lots of these strands are put together (and are then coated) they are called "optical cables".

Currently more than 80% of the world's long distance communications network traffic is carried over Optical Fiber cables. Fiber optic cables are different form the standard copper cables in three ways: Fiber optic cables are made out of glass (copper wires are made out of copper, obviously!); Fiber optic cables can carry more signals much quicker than copper wires can, as they use infra-red radiation; and Fiber optic cables are much more flexible, and lighter than copper cables

Fiber optic cables may sound great, as they are much faster, can carry more information and are more flexible, but they do have one fatal downfall, they are much more expensive - currently Fiber optic cables cost around four to five times the amount that copper cables do. This means that it is very expensive to change form copper to Fiber optic.

BT plans to upgrade 40% of UK homes to so-called 'Fibre to the Cabinet technology' (FTTC) by 2012, this gives Fiber optic like speeds, but on a copper wire. Because of the global economic downturn and UK recession, I think these plans may now have to be postponed to a later date.

I believe that Optical fiber is definitely the way forward in modern communications.
