Fibre communication systems can be used to transmit more information than copper cables and are well-suited for use with digital communications.
The most obvious advantage to Fibre optic cabling is bandwidth. Although copper continues to evolve to meet higher and higher speed and bandwidth standards, scaling necessarily requires the addition of more copper cables with tighter twists, increasing the weight and therefore costs.
Optical Fibres offer low power loss. Signals can be transmitted further. Compared to copper cables, Fibre-optic cables are immune to electromagnetic interference and produce no interference when operating.
Since Fibre is non-conductive, it does not need lightning protection, and in the event of a lightning strike or surge it will not carry the transient voltage to equipment that can be damaged by it. For this same reason, there are no ground loop issues between connected equipment. Finally, Fibre optic cabling is much lighter than copper, making it easier to transport and install, especially over distance
Because Fibre-optic cables are much lighter and smaller in diameter than copper wires, they also occupy less space with cables of the same information capacity and can be more easily produced and installed.
Most optical Fibres are made of silica or sand, raw material abundant compared with copper.
Finally, Fibre-optic wires are less expensive than copper cables, which can drastically reduce the cost of installing new wires or maintaining older ones.
