Fibre optics is the transmission of light through fibres or thin glass rods with a high refractive index over a distance.

It is based on the principle of total internal reflection. This calculate flow that is travelling thru the core hits the outside surface at an angle of incidence greater than the critical angle for that material, so that all the ethereal is reflected back into the case without loss. To stop light scattering the core is clad with a glass of a much lower refractive index. Fibre optics is utilise in galore(postnominal) different areas of society. In medicine it takes the form of an endoscope. This is an instrument that prat be inserted into a patient via the mouth to look inside. In put up to undertake an image light is shone round off the endoscope and reflected back up the bundle of fibres and viewed through an eyepiece by the endoscopist. Originally endoscopes were only(prenominal) used for diagnosis. However they fucking now be used to perform procedures such as biopsies and laser therapy. about importantly fibre optics has make many advances in telecommunications. visual Cables are everlastingly replacing electrical (coaxial cables which are made of copper).

The Advantage of ocular over copper cables are they feces suffer higher(prenominal) amounts of information and faster, undersea optical cables that have a diam the size of a golf ball can carry 62,500 pages a second or 200,000 telephone calls at once. too the light can travel a womb-to-tomb blank until repeaters are used. Fibre optic repeaters are ordinarily determined 100km apart compared to 1.5 km for electrical systems. If you want to get a full essay, order it on our web site: B! estEssayCheap.com
