8-shaped biological bite prevention optical cable

Abstract

The invention discloses a 8-shaped biological bite prevention optical cable, wherein the cross section of the 8-shaped biological bite prevention optical cable is 8-shaped; the 8-shaped biological bite prevention optical cable comprises a main cable core and a hanging cable core, wherein the main cable core and the hanging cable core are arranged in parallel and connected into a whole through a hanging belt, the main cable core is of a layer-stranded structure or a central tube structure without a central reinforcing piece, and the main cable core comprises optical fiber cores; the plurality of optical fiber cores are mutually twisted to form a cable, a water-blocking tape is wrapped outside the optical fiber cores, an FRP armor layer is wrapped outside the water-blocking tape, an outer sheath is wrapped outside the FRP armor layer, and an inner sheath is selectively arranged between the water-blocking tape and the FRP armor layer. According to the 8-shaped biological bite prevention optical cable provided by the invention, a full-dry water blocking mode is adopted for blocking water, round or flat rod-shaped fiber reinforced plastic FRP is used for armoring, the effects of preventing biological bite and improving the mechanical properties such as stretching and flattening of the optical cable are achieved, and the whole 8-shaped biological bite prevention optical cable is of an all-dielectric non-metal structure, free of metal conductors, and lightning-proof and electricity-proof. The cable can be applied to overhead laying in mountain forest regions and power scenes, andthe communication stability is guaranteed.

Description

Technical field[0001]The present invention belongs to the technical field of communication fiber optic cables, and more particularly to an 8-glyph antifalent engagement cable.Background technique[0002]As information demand continues to grow, fiber optic communication is widely used as a speed of the fastest and transmission quality. In the case of landslings, rural and other regions, the fiber optic cable is often used by birds, and the mouse, squirrel is often engaged in mice, which leads to communication interruption, especially the overhead layout of the forest area, and squirrels are attracted by the smell of the cable sheath and internal ointment. . Once the cable is destroyed, the loss of communication interruption and maintenance is unatristent.[0003]At present, in the optical cable communication, according to the laying method, the cable can be divided into three types of overhead, direct buried and pipelines. In the overhead cable, according to the gender, it can be divided...

AI Technical Summary

Problems solved by technology

At present, anti-biological optical cables are generally armored with stainless steel tape. The stainless steel tape can not only prevent rodents from biting through the optical cable, but also prevent damage caused by rust when the outer skin is damaged. It can solve the problem of biological bites very well, but Stainless steel tape as an armor layer increases the risk of lightning strikes, and for overhead optical cables, lightning protection is an important consideration

[0004] The traditional optical cable is filled with ointment in the casing and outside the cable core to block water. The advantage is that it can prevent water and moisture from entering the cable. The disadvantage is that the filling of ointment not only brings inconvenience to production, but also It also greatly increases the weight of the optical cable. Once the optical cable is broken, the smell of the ointment will attract rats such as squirrels to bite it, thereby aggravating the damage of the optical cable.

[0005] Most of the cores of existing optical cables adopt a conventional layer-stranded structure, and the loose tube is twisted around the central strength member, which increases the weight of the optical cable
