Optical cable with rat bite prevention function

Abstract

The invention relates to an optical cable with a rat bite prevention function. The optical cable comprises a cable core, a bite prevention net layer and an outer sheath layer which are sequentially sleeved from inside to outside, wherein the cable core comprises a central reinforcing member, a signal transmission body, a filling rope, a water-blocking tape layer, a cable paste filling body and an inner sheath layer, the signal transmission body comprises an optical fiber bundle, a fiber paste filling body and a loose tube, the signal transmission body and the filling rope are twisted on the central reinforcing member, and the water-blocking tape layer is sleeved in the inner sheath layer and winds and wraps the signal transmission body and the filling rope at the same time; the cable paste filling body is formed in the water-blocking tape layer and fills gaps among the central reinforcing member, the signal transmission body and the filling rope; the anti-biting net layer is sleeved between the inner sheath layer and the outer sheath layer. When the optical cable is bitten by rats, even if the teeth of the rats pierce the outer sheath layer, the teeth can be effectively prevented from going deep continuously under the blocking effect of the high-strength anti-biting net layer, so the optical fiber bundles used for transmitting signals are prevented from being bitten and damaged.

Description

technical field [0001] The invention relates to the technical field of communication optical cable manufacturing, in particular to an optical cable with the function of preventing rats from biting. Background technique [0002] As the demand for information continues to grow, optical fiber communication is widely used as the communication method with the fastest signal transmission speed and the best transmission quality. With the rapid development of network construction today, optical cables are increasingly widely used. [0003] It is known that in the actual application of the optical fiber cable, it is often bitten by rats to damage the optical fiber bundle, thereby causing the interruption of the signal transmission process. In recent years, a variety of rodent-proof optical cables have appeared on the market, and they have achieved good results in practical applications. After public information inquiry and physical inspection, it is found that the existing anti-rat...

Problems solved by technology

However, the above-mentioned technical solutions all have certain problems: 1) When the first embodiment is implemented, since a large amount of glass fibers are mixed into the fluid plastic for extrusion, it will not affect the smoothness of the subsequent extrusion process, and it will also seriously reduce the tensile strength of the outer sheath layer after molding, which will lead to side cracking in the subsequent transfer or cable construction process; shape

In the actual manufacturing and molding process of the cable, it is difficult to put the glass fiber anti-seize sleeve on the outer sheath layer, and it is necessary to use a special sheathing machine, which has a huge investment cost and a low molding rate; in addition, more importantly, , in the actual implementation of the laying operation of the cable, the glass fiber anti-seize sleeve with weak tensile strength is very easy to be damaged by the external pulling force or scratching force or break free from the outer sheath layer
