OPTICAL FIBRES
Fibre optics are thin strands of high-quality glass that carry data over long distances in infrared signals. Each strand is as thick as a human hair and is secured by a thermostatic coating. These fibre’s are then put together in a single cable that is flexible enough to be installed anywhere without breaking. In 1952 optical fibres was invented by a physicist Narinder Singh Kapany who managed experiments that led to the creation of optical fibres. A Japanese scientist names Nishizawa invented other sorts of technologies which was presented to the development of optical fibre communications, such as the graded-index optical fibre as a channel for passing on. light from semiconductor lasers. An optical fibre works when light travels down a fibre-optic cable by bouncing repeatedly off the walls. The process is called total infernal reflection, because the cladding does not absorb any light from the core, allowing the light to travel for a greater distance. Optical fibre’s are used in wide variety of different industries, few of them include of: In networking optical fibres are used to connect users and severs in a variety of network settings and help increase speed and accuracy of data transmission. Through medical it is used as light guides, imaging tools and also as lasers for surgeries. In telecommunications fibre is laid and used for transmitting and receiving purposes.
