What Fibre Optic Communication is.

Fibre optic communication refers to communicating via optical fibre. Fibre optic communications have a short history with very rapid development, and its impact has been felt in all aspects of communications. 


How it works.

Digitalised information is in high demand.  The need for it to sent quickly, and easily, is even higher.  The carrier of this information needs the highest bandwidth to send it with.  What determine's its badwidth? It's frequency.  And which carrier is the highest frequency? Light.  Light has the highest information carrying capacity, which is why we use it, along with optical fibres in communications networks.

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 com munications in core  networks in the developed world. The process of communicating using fibre-optics involves the following basic steps: Creating the optical signal involving the use of a transmitter, relaying the signal along the fibre, ensuring that the signal does not become too distorted or weak, receiving the optical signal, and converting it into an electrical signal.  This basic method has formed the basis for modern communications as we know it. Nowadays, with submarine fibre networks connecting the whole world, fibre optic communications allow us connect globally.
