Anvantage of optic fiber

Answer 1

Less expensive - Several miles of optical cable can be made cheaper than equivalent lengths of copper wire.

Higher carrying capacity - Because optical fibres are thinner than copper wires, more fibres can be bundled into a given-diameter cable than copper wires. This allows more phone lines to go over the same cable or more channels to come through the cable into your cable TV box.

Less signal degradation - The loss of signal in optical fibre is less than in copper wire.

Light signals - Unlike electrical signals in copper wires, light signals from one fibre do not interfere with those of other fibres in the same cable. This means clearer phone conversations or TV reception.

Digital signals - Optical fibres are ideally suited for carrying digital information, which is especially useful in computer networks.

Non-flammable - Because no electricity is passed through optical fibres, there is no fire hazard.

Lightweight and thin - An optical cable weighs less than a comparable copper wire cable. Optical fibres can be drawn to smaller diameters than copper wire. Fibre-optic cables take up less space in the ground.

Answer 2

Speed, as it is much faster than Copper wire, and distance which can go over 2 miles whilst Cat 6 can only go meters.
