A joint-type anti-double-bending optical cable for communication engineering

Abstract

The invention discloses a multi-section type anti-bending type optical cable for communication engineering, and belongs to the technical field of communication engineering. By virtue of the multi-section type anti-bending type optical cable for communication engineering, a body structure of bionic arthropods can be realized, and a traditional integral outer sheath structure of the optical cable isreplaced with a multi-section sub-sheath structure; meanwhile, the cooperation between a multi-direction swing rod and an interval limiting groove is utilized, so that on one hand, the rotating anglebetween every two adjacent sub-sheaths is limited within a safe range, and a wide rotating angle is replaced with multiple sections of small rotating angles in an overlaid mode, and large macro-bending of the optical cable is avoided; on the other hand, only a certain deformation angle of the single-section sub-sheaths is allowed, so that the large-scale micro-bending of the optical cable is avoided; and due to the fact that a cracking guide opening and remedial measures are arranged inside the multi-direction swing rod, irregular fracture caused by long-term compression of the multi-direction swing rod is avoided, the double-bending prevention effect on optical cable signal transmission is achieved, and the transmission loss and the probability of communication faults are remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of communication engineering, and more specifically relates to an arthropod-type anti-double-bend optical cable for communication engineering. Background technique [0002] Since entering the 21st century, the communication industry has developed rapidly, and optical cables are widely used in various fields. Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It uses one or more optical fibers placed in a sheath A communication cable assembly that acts as a transmission medium and can be used individually or in groups. The optical cable is mainly composed of optical fiber (glass filament as thin as hair), plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value. An optical cable is a communication line in which a certain number of optical fibers for...

Problems solved by technology

[0003] During the use of the optical cable, pay attention to avoid excessive bending. This is because the optical fiber inside the optical cable is realized by the principle of total reflection of light. If the line propagates forward, if the bending is too large, it will cause part of the light to fail to pass normally, which will lead to a decrease in optical power, which will cause signal loss. would result in huge losses

[0004] Generally speaking, the bending problem of the optical fiber in the optical cable is divided into two categories. One is the microbending of the optical fiber. The microbending of the optical fiber is generally caused by excessive pressure on the optical fiber. It is difficult to find with the naked eye, because it belongs to the microcosmic single point that is bent due to excessive force, and the other is the macrobend of the optical fiber. All optical cables have their own minimum bending radius, and the bending loss of the optical cable within the minimum bending radius is almost It can be ignored, but often in the actual use process, the stress of the optical cable is very complicated, and the microbending and macrobending of the internal optical fiber are inevitable. Once the amplitude is too large, transmission loss or even communication failure is prone to occur. Communication Engineering Brings Huge Loss
