Description

Communication cable optical cable with exhaust function

Technical Field

Background

The communication product mainly comprises wired communication equipment and wireless communication equipment. The wired communication equipment mainly introduces conversion equipment for solving serial port communication, professional bus type communication, industrial Ethernet communication and various communication protocols in industrial fields. The wireless communication equipment mainly comprises wireless AP, a wireless network bridge, a wireless network card, a wireless lightning arrester, an antenna and the like.

The communication optical cable is composed of a core and an outer sheath, wherein the core is composed of a plurality of (core) optical fibers (generally from a few cores to a few thousands of cores). Compared with the traditional symmetrical copper loop and coaxial copper loop, the optical fiber has the advantages of much larger transmission capacity, less attenuation, long transmission distance, small volume, light weight, no electromagnetic interference and low cost, and is the most promising communication transmission medium at present. It is being widely used for signal transmission of various departments of telecommunication, power, broadcasting and the like, and will gradually become a main body of future communication networks. The main difference between the optical cable and the electric cable is that the optical cable must have a strength member to withstand external mechanical loads in order to protect the optical fiber from various external mechanical forces.

Because communication optical cable when using, have the overwhelming majority to need to expose in outdoor eminence position, be difficult to transport when density is great and build, because the filler is organic compound, produce gas easily under the adverse external environment for a long time, cause the damage to the optical fiber.
