Fibre optic cables have gradually taken over as the transmission medium in local area networks as public telephone and data networks. Compared with electrically conductive cables are fibre-optic cables superior properties with respect to the range and bandwidth. The base material is glass and in some cable types of plastic. The cables therefore contain no metal and uses light transmission. Light waves have much greater bandwidth than electrical waves when the light wavelength is very short and the frequency correspondingly high. Fibre-optic cables can therefore transmit with much higher data rate, with tens of gigabits per second. Compared to twisted pair cables and coaxial cables are the benefits many. Advantages of fibre-optic: • Very high bandwidth and binary speed • Does not conduct electricity •…show more content…
It is a measure of how much the speed is reduced through the material relative to the vacuum. Wave lengths Wave lengths is the distance between two waves in a given period. Simply explained, its the length of the straight line between the two wave crest, but the wavelength can easily be measured at any other point of a wave. Precaution steps by working with fibre-optic cables and systems Laser light are used in fibre-optic cables. Laser light is divided into different categories according to their degree of dangerousness. The laser who are used in fibre-optic cables can be harmful to eyes and skin. • Never look into the end of a fibre. • Never look into laser diode or detectors or equipment for these components. The light is invisible, but will still be harmful. • Hold the fibre-optic cable well away form the eyes to prevent damage from the sharp fibre ends. • Protect yourself from injuries, like prick in the skin from fibre ends and fibre cuts. It can penetrate the skin and blood vessels without notice. • Fibre residues must always be in a suitable place in separate
