Optical fiber is fibre-optic writing a Chinese character in simplified form, and is a kind of fiber be made up of glass or plastics, can be used as light conduction instrument.Transmission principle is ' total internal reflection of light '.First front Hong Kong Chinese University principal Gao Kunhe George A. Hockham proposes the imagination that optical fiber may be used for communication transfer, and therefore high Kun obtains Nobel Prize in physics in 2009.In daily life, because light is more much lower in the loss of electric wire conduction than electricity in fibre-optic conduction loss, optical fiber is used as the information transmission of long distance.
Usual optical fiber and optical cable two nouns can be confused.Most optical fiber before use must be coated by which floor operator guards, and namely the cable after coated is called as optical cable.The protective cover of fiber outer layer and insulating barrier can prevent surrounding environment to the injury of optical fiber, Ru Shui, fire, electric shock etc.Optical cable is divided into: cable skin, aramid fiber yarn, cushion layer and optical fiber.Optical fiber is similar with coaxial cable, does not just have mesh shields layer.Center is the glass core that light is propagated.
Optical fiber used in current communication is generally silica fibre.The chemical name of quartz is silicon dioxide (SiO2), and it is identical with our the daily main component being used for building a house sand used.But the optical fiber that common quartz material is made can not be used for communicating.Telecommunication optical fiber must be made up of the material of very high purity; But, mix the dopant of trace, the ratio of refraction of fibre core and covering can be made slightly different in material of main part, this is conducive to communication.
The bandwidth of Optical Fiber Transmission information, within every 6 months, increase by 1 times, and price reduces by 1 times.The development of optical communication technique, extraordinary basis has been established in the development for Internet broadband technology.This is just for large-scale cable television system adopts Optical Fiber Transmission mode to clear away last obstacle.Because material (quartz) source making optical fiber is very abundant, along with the progress of technology, cost also can reduce further; And copper raw material needed for cable is limited, price can be more and more higher.Obviously, Optical Fiber Transmission will have comparative advantage from now on, become and set up the whole province, so that the main transmission media of national cable TV network.
