Since over 30 years ago first fiber optic data cable installed and applied for commercial wise,now, with the technique-ment of fiber optic, and also the competitive cost of the complete range of optic devices, to fulfill the high speed data network & telecommunication, definitely will be on its duty. Optic Fiber -Made by the most common substance, silicon dioxide ( SiO 2 ) in complete core diameter 9um - single mode, 62.5um - OM1,50um - OM2/OM3, and with 125um refraction cladding, to afford light singnal transmission supports long distance and high speed data network & telecommunication. Technology -To use the light to transmit the signals from one place over optic fiber, is due to the light propagates through the fiber with little attenuation also immune to electromagnetic interference. These advantages also contribute to fiber optic development and practical application. Wide Area Network -Since the beginning of fiber optic application,...
