Optical fiber cable is manufactured to meet the performance specifications of optics, mechanics or environment. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as the transmission medium and can be used alone or in groups. Optical cable is mainly composed of optical fiber (glass fiber as thin as hair) and plastic protective sleeve and plastic outer skin. There is no metal such as gold, silver, copper and aluminum in the optical cable. Optical cable is a communication line that a certain number of optical fibers are formed into a cable core in a certain way, and some are also covered with an outer sheath to realize the transmission of optical signals. That is: a 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. In addition, there are waterproof layer, buffer layer, insulated metal wire and other components as needed.
