Fibre-optic communication is a
method of transmitting information from one place to another by
sending pulses of light through an optical fibre. The light forms an
electromagnetic carrier wave that is modulated to carry information.
First developed in the 1970s, fibre-optic communication systems have
revolutionized the telecommunications industry and have played a
major role in the advent of the Information Age.
Because of its
advantages over electrical transmission, optical fibres have largely
replaced copper wire communications in core networks in the
developed world. Benefits of fibre are detailed below:
|
High bandwidth over long distances – Supports speeds
in excess of 100 Gigabits. |
|
|
Less signal degradation - The loss of signal in
optical fibre is less than in copper wire. |
