An optical fiber cable is fabricated to meet optical, mechanical, or environmental performance specifications using one or more optical fibers placed in a jacketed jacket as a transmission medium and can be used either individually or in groups Cable assemblies. Fiber optic cable mainly by the optical fiber (as thin as the hair of the glass wire) and plastic protective casing and plastic skin composition, fiber optic cable is not gold, silver, copper and aluminum and other metals, generally no recovery value. Fiber optic cable is a certain amount of fiber in accordance with a certain way to form a cable core, outsourcing jacket, and some also cover the outer layer, in order to achieve optical signal transmission of a communication line. That is: by the optical fiber (optical transmission carrier) through a certain process to form the cable. The basic structure of the cable is generally by the cable core, to strengthen the wire, filler and sheath, and other parts of the other, as required, waterproof layer, buffer layer, insulated metal wire and other components.
