Most of us have heard of the term. But in the end is what, maybe you don't know, so many small a thread will be able to transmit data, we listen to music, watch movies are brought in a small thread, even now the wireless network directly to the line are also omitted. So what is it?

       Fiber optic cable is mainly by optical fiber (fine hair glass silk, for example) and a plastic protective sleeve and plastic sheath structure, fiber optic cable, no gold, silver, copper and aluminum and other metals, generally there is no recycling value. Optical cable is a certain amount of fiber in a certain way to form a cable core, outsourcing has a sheath, and some also covered the outer sheath, in order to realize the optical signal transmission of a communication line. A cable that is formed by an optical fiber (optical transmission carrier) through a certain process.

  In 1976, the United States Baer Institute in Atlanta, built the first fiber optic communication experiment system, the use of the Western Electric Co to produce 144 fiber optic cable containing fiber optic cable. In 1980, the commercial optical fiber cable made of multimode fiber began to use in the city board trunk line and a few long-distance lines. The commercial optical fiber cable made of single mode optical fiber is adopted in 1983. 1988, connecting the United States and the British law between the first across the the Atlantic submarine cable laying success, and soon built the first submarine cable across the Pacific ocean. In 1978, China developed a communication cable, the use of multimode fiber, cable structure for the layer of the heart. Has been in Beijing, Shanghai, Wuhan and other places to carry out the field test. Shortly after the city in the telephone network as a trunk line trial, after 1984, gradually used for long-distance lines, and began to use a single mode fiber. Optical fiber communication than copper wire with greater transmission capacity, long relay distance, small volume, light weight, no electromagnetic interference, since 1976, has developed into a trunk, intracity relay, offshore and transatlantic submarine communications, and local area network and special network as the backbone of the wired transmission line, and began to developments in the fields of local subscriber loop distribution network, optical fiber to households, width generation integrated services digital network provides a transmission line.
