Optical cable with bird pecking and rat bite prevention functions and production method thereof

Abstract

The invention discloses an optical cable with bird pecking and rat bite prevention functions and a production method thereof. The optical cable comprises a plurality of optical fibers, water-blocking fiber paste, a plurality of loose tubes, a central reinforcing piece FRP, water-blocking yarn, a first water-blocking tape, an armored FRP rod, an outer sheath and a one-way spiral red color strip. Wherein the loose tubes are arranged outside the plurality of optical fibers, the water-blocking fiber paste is located in the loose tubes and located among the plurality of optical fibers, the plurality of loose tubes are fixed on the central reinforcer FRP in an SZ twisting mode, the water-blocking yarn is arranged between the loose tubes and the central reinforcer FRP, the first water-blocking tape is arranged outside the plurality of loose tubes, and the second water-blocking tape is arranged outside the plurality of optical fibers. The armored FRP rod is armored outside the water-blocking tape in a one-way spiral mode, the outer sheath is arranged on the periphery of the armored FRP rod, and the one-way spiral red color bar is arranged on the outer sheath. Compared with the prior art, the bird pecking prevention and rat bite prevention effects are improved, and the production and installation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of outdoor communication optical cables, in particular to an optical cable with anti-bird pecking and rat-biting functions and a production method thereof. Background technique [0002] Because of the fragility of optical fibers in communication cables, complete, high-strength, and durable protection measures are particularly important for their communications. During the design, installation and use of optical cables, the prevention of environmental damage is an important consideration, and one of the main influencing factors is rodents and birds. The characteristic of rodents is that they need to grind their teeth continuously, and the hardness and composition of the optical cable sheath may be more suitable for rodents to bite. In addition, overhead communication optical cables, especially in fields and forests, are also severely damaged by bird pecking. Therefore, in outdoor communication optical cable...

AI Technical Summary

Problems solved by technology

[0003] At present, in the communication optical cable industry, in terms of preventing bird pecking, metal tape armoring is often used to strengthen, install circuit design and protection, or simply color sheathed optical cables. Or use chemical methods, such as sheathing materials containing capsaicin, but the production and installation costs of these methods are relatively high, and the protective effect is not long-lasting
