What's optical cable?

Optical fiber cable (Optical fiber cable) is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable component that uses one or more optical fibers placed in a covering sheath as the transmission medium and can be used individually or in groups. Optical fiber cable is mainly made of optical fiber (fine like hair of glass filament) and plastic protective sleeve and plastic skin, optical cable no gold, silver, copper aluminum and other metals, generally no recovery value. Optical cable is a kind of communication line in which a certain number of optical fibers are composed of a cable core in a certain way, which is covered with a sheath, and some of them are also covered with an outer sheath to realize optical signal transmission. That is, the cable formed by optical fiber (optical transmission carrier) through a certain process. The basic structure of optical cable is generally composed of cable core, reinforcing steel wire, filler and sheath and other parts, in addition, according to the need for waterproof layer, buffer layer, insulating metal wire and other components.
