Cable is in order to meet the performance specification for optical, mechanical or environmental and manufacturing, it is used in coating sheath in one or more optical fiber as transmission medium and communication cable components used singly or in groups. The cable is mainly composed of an optical fiber (such as fine hair glass) and a plastic protective sleeve and plastic casing, the cable is a certain amount of fiber in a certain way to the heart of the composition of cables, wrapped in a sheath, some also cover the outer protective layer, to achieve a communication line optical signal transmission. The basic structure of optical cable is usually composed of cable core, reinforcing steel wire, filling material and sheath. In addition, there are waterproof layer, buffer layer, insulated metal wire and so on.

Fiber optic cable type

1, in accordance with the transmission performance, distance and use of different, fiber optic cable can be divided into user, local, optical, long-distance fiber optic cables and submarine fiber optic cable.

2, in accordance with the different types of fiber optic cable used, fiber optic cable can be divided into single-mode and multi-mode fiber optic cable.

3, in accordance with the number of fiber optic fiber core cable, fiber optic cable can be divided into single core fiber optic cable, double core fiber optic cable and so on.

4, in accordance with the different methods of strengthening the configuration, fiber optic cable can be divided into central reinforcement components, optical fiber cables, scattered reinforcement components, fiber optic cables, protective layer reinforcement components, fiber optic cables and integrated external protective layer optical fiber cable.

5, in accordance with the transmission conductor, medium conditions, optical cable can be divided into non metallic fiber optic cable, ordinary optical fiber cable, integrated optical fiber cable (mainly used for railway network communication network).

6, according to different laying methods, optical fiber cable can be divided into pipeline, direct buried optical fiber cable, aerial cable and submarine fiber optic cable.

7, in accordance with the different structure, optical fiber cable can be divided into flat structure, fiber optic cable, layer twisted fiber cable, frame type fiber optic cable, armored fiber optic cable and high-density user fiber optic cable.
