Rat-proof optical cable with braided glass fiber tape

Abstract

A rat-proof optical cable with a braided glass fiber tape comprises a cable core, a braided layer and a sheath, the braided layer is sleeved on the outer side of the cable core, the sheath is sleevedon the outer side of the braided layer, the braided layer is composed of multiple glass fiber tape layers, the sheath comprises a polyethylene inner sheath and a nylon outer sheath, and non-metal reinforcer FRP rods parallel to the cable core are symmetrically arranged in the polyethylene inner sheath. The optical cable is free of any metal materials and all-dielectric materials, it is guaranteedthat the optical cable is light in weight and small in size and has natural shielding performance on thunder and strong current, a double-protection mechanism of multi-layer woven glass fiber tape wrapping and nylon outer protection is adopted, and nylon materials have shore hardness larger than 65, are smooth and resistant to abrasion and have excellent physical characteristics on bite of small voles; and the quartz glass silk is high in tensile strength and has a special physical defense effect, the body, especially the mouth of an animal, is stabbed and abandoned without being bitten continuously, the material cannot be rusted due to exposure, the environment cannot be polluted, and damage to the cable caused by common mice can be perfectly avoided.

Description

technical field [0001] The invention relates to the technical field of communication optical cables, in particular to a rat-proof optical cable with braided glass fiber tape. Background technique [0002] The country's substantial investment in the communications industry aims to improve the quality of communications while ensuring full coverage of communications. When laying optical cables, many of them pass through forested and mountainous areas. These areas are populated by rodents such as mice. Due to rodent Due to the living habits of animals, it is easy to cause damage to optical cables in use, resulting in communication failures. How to avoid rodent infestation, cable designers have also adopted a variety of rodent-proof methods, including chemical rodent-proof by adding chemical agents, and strengthening methods with hard materials such as stainless steel and steel wire armor. Each method has its own advantages, but the disadvantages are also Obviously, chemical mat...

[0002] The country's substantial investment in the communications industry aims to improve the quality of communications while ensuring full coverage of communications. When laying optical cables, many of them pass through forested and mountainous areas. These areas are populated by rodents such as mice. Due to rodent The living habits of animals can easily cause damage to optical cables in use, resulting in communication failures

How to avoid rodent infestation, cable designers have also adopted a variety of rodent-proof methods, including chemical rodent-proof by adding chemical agents, and strengthening methods with hard materials such as stainless steel and steel wire armor. Each method has its own advantages, but the disadvantages are also More obviously, chemical materials are not good for environmental protection. Excessive use of heavy armor will greatly increase the weight of optical cables, increase manufacturing costs and processing difficulties, and greatly increase the difficulty of construction and use and maintenance.
