What Is Fibre Optic Communication?

Fibre optic communication is the transfer of data using light waves through glass tubes. These light waves or pulses are detected at the receiver end and converted back to electrical information in forms of computer readable 0s and 1s. The information may be modulated onto the carrier light wave or simply be sent as presence of pulse equating 1 and absence 0. This new technology is the largest growing and rapidly employed means of data transmission for networks and long distance communication.

The exchange of data and information at this moment is the highest it has been in all history of mankind and the trend continues to rise. For such large and incredibly fast traffic of data, superior characteristics of fibre optics have made the copper wire cables obsolete. Copper wires are prone to disturbances from various external factors including EMF interference and the extreme vulnerability to tapping of information. Fibre optic communication solves these issues completely.

These cables consists of bundles of glass tubes through which the light waves (carrying the information) travel. These glass tubes are coated from the inside with reflective material which restrains any light waves from ‘leaking’ out of the tube. It also makes the glass tube completely isolated preventing any interference with external signals. If any attempt is made to breach the physical tube, the light leaks and any such breaches to security can be immediately recognized. Hence these cables are virtually impossible to tap.
