Rat-proof optical cable for mountain areas

Abstract

The invention relates to the technical field of rat-proof optical cables, and discloses a rat-proof optical cable for mountain areas. The rat-proof optical cable for mountain areas comprises a reinforced middle core, wherein the surface of the reinforced middle core comprises a loose casing and a cable core filling, the loose casing is on the surface of the reinforced middle core, the left of thesurface of the loose casing and the right of the surface of the reinforced middle core are fixedly connected, the cable filling is on the surface of the loose casing, the inner wall of the cable corefilling and the surface of the loose casing are fixedly connected, the inner wall of the cable core filling and the surface of the reinforced middle core are fixedly connected, and the surface of theloose casing comprises an inner jacket, an anti-torque force layer and an asbestos layer. In the rat-proof optical cable for mountain areas, the anti-torque force layer is arranged on the surface of the inner jacket, so as to prevent a cable from bending in cabling; a material outer thin layer and a thin layer thorn cone are arranged on the inner wall of an outer jacket, so as to prevent rat-dispelling material filling from volatilizing in production and transportation to shorten rat-dispelling duration.

Description

technical field [0001] The invention relates to the technical field of anti-rat optical cable, in particular to an anti-rat optical cable used in mountainous areas. Background technique [0002] An optical cable is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. The optical cable is mainly composed of optical fibers (glass filaments as thin as hair) and plastic protective sheaths. The optical cable is composed of a certain number of optical fibers in a certain way to form a cable core, and is covered with a sheath, and some are also covered with an outer sheath to realize a communication line for optical signal transmission. Ordinary optical cables are usually laid with Underground or erected at high altitude by electric poles, but there are many rugged and jungle roads in mountainous areas. It is difficult to erect optical cables by electric poles, and it is difficult ...
