Abstract

The invention discloses a rat-proof optical cable and a manufacturing method thereof, and relates to the technical field of optical cable manufacturing, the rat-proof optical cable comprises an optical cable main body, the optical cable main body comprises a cable core and a composite inner protection layer and a main body outer protection layer which wrap the outer side of the cable core from inside to outside, and a repelling layer is arranged between the composite inner protection layer and the main body outer protection layer. The composite inner protective layer is coated with the repelling layer, the repelling layer is coated with the main body outer protective layer in an extrusion molding manner, the repelling layer comprises a carrier material for the optical cable and a repelling agent, and the repelling agent is adhered to the carrier material in a bonding or coating manner to form the repelling layer in which the repelling agent is combined with the carrier material; and by implementing the technical scheme, the technical problem that the existing overhead laying optical cable is poor in capability of protecting mouse animals from biting can be effectively solved, the communication line construction design does not need to be changed when the optical cable is applied to optical cable line construction or maintenance, and the protection measure for preventing the mouse animals from biting off the optical fiber when the optical cable is overhead laying application is simplified, and the manufacturing and use cost of the rat-proof optical cable is reduced.

Description

technical field [0001] The invention relates to the technical field of optical cable manufacturing, in particular to a rat-proof optical cable with a repellent layer and a manufacturing method thereof. Background technique [0002] At present, in optical fiber communication lines, a large number of optical cables adopt different installation methods such as overhead, pipeline, and direct burial according to different line environments. The performance of the optical cables corresponding to the installation methods is different, and the structural differences of the optical cables form different models and characteristics. In the practice of optical cable line operation and maintenance, optical cables are laid overhead through mountainous forest areas, and there are many cases of communication interruption accidents caused by squirrels and other rodents biting optical cables. Communication operators put forward the demand for rodent-proof optical cable products. The company h...
