Anti-rodent optical cable and manufacturing method thereof

Abstract

The invention provides an anti-rodent optical cable and a manufacturing method thereof, and relates to the technical field of manufacturing of anti-rodent optical cables. Structurally, a fixing measure for preventing a lap joint part of steel tape armor layers of GYTS and GYTS04 type optical cables from being peeled off by rodents is added. The anti-rodent optical cable comprises a polymer jacket,an embossed plastic-coated steel belt, a winding steel wire, a cable core, a bonding hole and a steel belt lap seam. According to the invention, the protection measure of preventing rodents from biting off optical fibers during overhead laying application of the optical cable is simplified, installation, protection, maintenance and the like of the optical cable are simplified, and the productionand use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of rodent-proof optical cable manufacturing, in particular to a rodent-proof optical cable and a manufacturing method thereof. Background technique [0002] The construction of optical fiber communication network requires a large number of optical cable products with various performances. The environment of field optical cable line installation is ever-changing, which puts forward special requirements for optical cable design and processing. At present, there are many situations where optical cables are laid overhead through mountainous forest areas. During the installation and use of optical fiber cables, the laying path is tortuous and the optical cables are in a bent state. For commonly used steel tape armored optical cables such as GYTS type and GYTS04 type, the bending state is Stress can easily cause the inner and outer layers of the steel tape to separate. The key is that the optical cable erected in ...

Problems solved by technology

At present, there are many situations where optical cables are laid overhead through mountainous forest areas. During the installation and use of optical fiber cables, the laying path is tortuous and the optical cables are in a bent state. For commonly used steel tape armored optical cables such as GYTS type and GYTS04 type, the bending state is Stress can easily cause the inner and outer layers of the steel tape to separate. The key is that the optical cable erected in the mountainous forest area is easily damaged by rodents. After the outer PE sheath is gnawed off by rodents, the armored steel tape is separated. , Rodents can easily peel off the lap joints of steel tapes, the cable core will lose the protection of steel tape armor and be bitten by rodents, the loss of optical fibers in the cable will increase or be directly bitten off, resulting in communication safety accidents and major losses

[0003] For the situation where the optical cable is attacked by rodents, the typical protective measures taken by all parties are as follows: the key areas of the optical cable line are protected by external protective sleeves to prevent rodent attacks; the optical cable structure is added with double armor layers to prevent rodents from biting Cable core; use biological repellent substances to add to the cable sheath to prevent rodents from approaching; use electromagnetic / electroacoustic technology to drive rodents; the above protective measures increase construction and maintenance costs, or the technology is complicated, or there is a risk to personal safety, or high product cost
