OPTICAL FIBRE COMMUNICATIONS

Optical Fibre: A flexible optically transparent fiber, as of glass or plastic, through which light can be transmitted by successive internal reflections.
Optical fibres are fine threads of glass which are capable of transmitting light at about 2/3 the speed of light in vacuum.
Optical Fibre provides the greatest "Information - Carrying - Potential" of any available medium today.
Optical fibres are a key element in light wave communication.
A fibre is thinner than a human hair but is very strong and takes less room than an ordinary cable.

The main job of an optical fibre is to guide the light (which carries the information) with minimum attenuation or loss of the signal. It offers the most efficient medium for transmitting digitally formatted information from one point to another. An Optical Fibre guides a coded series of light pulses down a path in which none of the information - carrying light signal is lost. Optical fibre cables have a much greater bandwidth than metal cables (that is they transmit more data) and they are less susceptible to interference. Fibre optics technology is relatively new and because of its high efficiency, optical fibre cables are steadily replacing the traditional lines. Currently all new undersea cables are made of optical fibres With the arrival of cable TV systems, optical fibre is getting closer to your home.
