Background

Optical fiber cables (optical fiber cables) are manufactured to meet optical, mechanical, or environmental performance specifications and are telecommunication cable assemblies that utilize one or more optical fibers disposed in a surrounding jacket as the transmission medium and that may be used individually or in groups. The optical cable is mainly composed of optical fibers (thin glass filaments like hair), a plastic protective sleeve and a plastic sheath, and metals such as gold, silver, copper and aluminum are not contained in the optical cable, so that the optical cable generally has no recycling value. The optical cable is a communication line which is formed by a certain number of optical fibers according to a certain mode to form a cable core, is coated with a sheath, and is also coated with an outer protective layer for realizing optical signal transmission. Namely: a cable formed by subjecting an optical fiber (optical transmission carrier) to a certain process. The basic structure of the optical cable generally comprises a cable core, a reinforcing steel wire, a filler, a sheath and other parts, and further comprises an organic solvent prevention layer, a buffer layer, an insulated metal wire and other components according to requirements. 1) Optical cables can be classified into subscriber cables, city cables, long-distance cables, and submarine cables according to transmission performance, distance, and use. 2) Optical cables can be classified into single-mode optical cables and multi-mode optical cables according to the type of optical fibers used in the optical cables. 3) The optical cable can be divided into a single-core optical cable, two core optical cables and the like according to the number of optical fiber cores in the optical cable. 4) Optical cables can be classified into a central strength member optical cable, a distributed strength member optical cable, a sheath strength member optical cable, and a composite outer sheath optical cable according to the strength member disposition method. 5) Optical cables can be classified into metal-free optical cables, ordinary optical cables and comprehensive optical cables (mainly used for railway special network communication lines) according to different conditions of transmission conductors and media. 6) Optical cables can be divided into pipeline optical cables, direct-buried optical cables, aerial optical cables and ethanol-bottom optical cables according to different laying modes. 7) According to different structural modes, the optical cable can be divided into a flat-structure optical cable, a layer-stranded optical cable, a skeleton optical cable, an armored optical cable and a high-density user optical cable.
