Self-crack-repairing type low-failure-rate optical cable for network engineering construction

Abstract

The invention discloses a self-crack-repairing type low-failure-rate optical cable for network engineering construction. The invention belongs to the technical field of network engineering. Accordingto the invention, after a protective coat is cracked, external air quickly enters along a crack and is in contact with a crack repairing ball preset in a crack repairing layer; the crack repairing action of the crack repairing ball is triggered; the crack sealing ball firstly automatically heats to enter the crack; an opening film is punctured based on the characteristic that a memory crack sealing wire absorbs heat and begins to deform; at the moment, a two-component thermosetting adhesive is extruded and released and is converged and fused in the crack; the protective coat in the crack areastarts to be plasticized due to heat; the memory crack sealing wire can smoothly penetrate into the protective coat, the memory crack sealing wire firstly restores the shape of the fishhook along withthe gradual cooling of the crack sealing ball, the crack area is cured and bonded together under the action of the adhesive, the action similar to needle and thread crack sealing is achieved, the repairing strength of the crack can be remarkably improved, and the secondary cracking phenomenon is prevented.

AI Technical Summary

Problems solved by technology

[0005] In the integrated wiring in network engineering, the optical cable is undoubtedly the most critical link. Considering the layout requirements and processing costs, most of the existing optical cables are protected by plastic. When affected by external forces and weakened mechanical strength, etc., Cracks are prone to occur. Once the optical cable cracks, not only its own strength will be significantly reduced, but also external factors such as rain, dust, etc. are more likely to invade the interior of the optical cable and cause erosion and damage, which seriously interferes with the normal communication of the optical cable, especially in network engineering. In the key communication nodes, high stability and high security data communication is necessary and important, and traditional optical cables obviously cannot deal with common cracking problems
