What is fiber optic cable

Fiber optic cables are manufactured to meet optical, mechanical, or environmental performance specifications, and are telecommunication cable assemblies that utilize one or more optical fibers in a sheathing as the transmission medium and can be used individually or in groups. Optical cables are mainly composed of optical fibers (glass filaments as thin as hair), plastic protective sleeves and plastic outer skins. There are no metals such as gold, silver, copper and aluminum in the optical cables, and generally have no recycling value. Optical fiber cable is a kind of communication line in which a certain number of optical fibers form a cable core according to a certain method, which is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. That is: a cable formed by an 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, etc. In addition, there are waterproof layer, buffer layer, insulated metal wire and other components as needed.
