Fibre Optic Technology

back to products and services »

Fibre optics is a technology whereby a signal like video, data or audio, is modulated on a light beam and sent down a glass tube over large distances, with very little attenuation and loss. It also offers very high bandwidths compared to copper wire.

The bandwidth of a fibre optic cable is between 100Mhz and 1000MHz compared to a copper wire, which can handle only 3 to 20 MHz. This large bandwidth allows many applications and uses of fibre optics such as video, audio etc. It is possible to send up to 200 video signals on a signal fibre optic cable (using the correct transmission equipment), which is impossible with a copper wire.

Unlike coaxial cable, which uses electric currents, fibre optics uses light, making it immune to any type of interference. As light is the medium of transmission, a fibre optic cable does not pick up Electro Magnetic Interference (EMI). EMI is the biggest source of problems with co-axial cable. Double images, moving lines, horizontal bands and picture snow in a video picture are due to EMI. All these are eliminated with the use of fibre optics as voltage has no effect on a light beam.

Due to the many advantages that fibre optics has over conventional copper wire, we regularly install this medium to transmit video, audio and data for use with some of our systems.

We carry out all of this work in house without the need to sub contract to specialist companies. ESS owns all relevant equipment to allow us to splice and test fibre cables.
