ADVANTAGES OF FIBER OPTIC
Fibre Optic signal transmission offers many advantages over existing metallic links. Some of these are:
1. Large Bandwidth
Fiber optic offers very high bandwidths as compared to copper wire. The bandwidth of a fiber optic cable is between100Mhz to 1000 MHz as compared to a copper wire, which can handle only 3 to 20 MHz. This large bandwidth allows many applications and uses of fiber optic. For example, a video signal has a bandwidth of 5 MHz. It is, therefore, possible to send up to 20 - 200 video signals on a single fiber optic cable. This is impossible with copper wire. In fact, by using digital compression techniques you could modulate up to 500 - 1000 video signals on a single F/O cable.
2. No Interference
Unlike coaxial cable which uses electric currents, fiber optic uses light making it immune to any type of interference
