Optical transmission has several advantages over copper wire: optical fibre's high bandwidth means that a lot more data can be transmitted faster.
A pair of copper wires (which is what most houses in urban areas use for the initial point of access to the Internet can transmit two telephone calls simultaneously, while a single optical fibre can transmit over80,000; glass is cheaper and lighter than copper; optical fibre is unaffected by electro-magnetic interference, and so is ideal in electrically "noisy" environments, eg where there is high voltage equipment nearby; no electrical current is transmitted down a fibre (glass is a good insulator), so it is suitable in hazardous environments where electrical discharge would dangerous; as transmission technology continues to improve, higher and higher bandwidths are possible over the same optical fibre links without having to replace the cables.

Because they can carry many times as many signals, with far less degradation of the signals.
One pair of optical fiber cables can carry thousands of telephone conversations with better clarity and requiring far fewer amplifiers along its path.

Becuase Fiber optic cables:

do not break as easily.

 

Light cannot catch on fire.

 

are impervious to electromagnetic interference (EMI).

 

transmission results in less attenuation.

 

transmission is faster

IT IS LOW COST THAN COPPER AND BETTER AND SAFE FASTEST WAY OF COMMUNICATION
