Q.What is meant by Fiber optic communication?

In fibre optic communication the message is carried not by electrical signals on wires or by radio waves, but by light travelling through a thin transparent cable. …

[!TLDR]

Fibre optic communication carries information on a light beam guided through a glass or plastic fibre optic cable.

A fiber optic communication system uses light as the carrier of the information to be transmitted. The medium of propagation is a light 'pipe' or waveguide known as the fiber optic cable, usually made of glass or plastic. This medium can transmit large amounts of information over a very wide bandwidth: while hundreds of telephone conversations can be sent at microwave frequencies, many thousands of signals can be carried on a single light beam in a fibre. Using multiplexing techniques, fibre optic communication offers almost lim …
