The Optical Fibre
Optical fibre is the newcomer in telecommunications.

Glass has been used as a material for centuries, and its fabrication was well developped.
It is was known that light could be guided through a glass fibre: the only problem was the quick attenuation of light.

It is not until 1970 that a low-loss fibre was manufactured giving birth to fibre optics communications.
Optical fibre cables have a much greater bandwidth than metal cables (that is they transmit more data) and they are less susceptible to interference.
A fibre is thinner than a human hair but is very strong and takes less room than an ordinary cable.

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.
