According to the different environment, fiber optic cable is generally divided into indoor cable and outdoor cable, indoor cable is formed by a certain process of cable, mainly by the optical fiber (such as hair glass) and plastic protective casing and plastic skin composition. Outdoor cable is a communication line to achieve optical signal transmission. By a certain number of fiber in accordance with a certain way to form a cable core, outsourcing jacket, and some also cover the outer layer. Mainly by the optical fiber and plastic protective casing and plastic skin composition. The tensile strength of the indoor fiber is small, the protective layer crosses, but relatively lightweight, economical, mainly used in horizontal cabling subsystems and vertical trunk subsystems. Outdoor cable tensile strength is greater, the protective layer is more heavy, and usually armored (that is, metal skin wrapped). Outdoor cable is mainly used between buildings, as well as the interconnection betw...
