Self-supporting branch optical cable capable of night identification

Abstract

The present invention provides a self-supporting branch optical cable capable of night identification, belonging to the technical field of cable. The cable comprises a suspension wire, main cables, afirst connection rib, a second connection rib, a third connection rib and lighting strips, there are three main cables which are arranged at one side of the suspension wire in a triangular shape and are connected with the suspension wire respectively through the first connection rib, the second connection rib and the third connection rib, the first connection rib and the second connection rib aresymmetrically distributed relative to the third connection rib, there are at least two lighting strips which are arranged on the first connection rib and / or the second connection rib and / or the thirdconnection rib and / or the main cable. The lighting strips can perform self lighting at night with different colors to facilitate identification of each main cable in a night dark environment, and thelighting strips cannot be subjected to lighting friction with a pipeline in the construction process, and are not easy to be worn and damaged so as to effectively improve the service life; and moreover, the main cables employ three center pipe-type cables with the same structure, and the fiber optic capacity is three times of a common optical cable.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a self-supporting bifurcated optical cable that can be identified at night. Background technique [0002] With the continuous improvement of people's requirements for communication speed and quality, my country's optical communication industry has achieved great development. Optical cables usually have installation methods such as overhead, pipeline, and direct burial, among which overhead laying is divided into self-supporting and non-self-supporting. Self-supporting optical cable refers to the optical cable whose self-strengthening components can bear its own weight and external load. Due to the excellent load-bearing performance of the optical cable itself, it does not need additional steel strands for support. It can be laid at one time, saving construction costs and maintenance costs. Existing self-supporting optical cables are usually composed of suspension wire...

AI Technical Summary

Problems solved by technology

Existing self-supporting optical cables are usually composed of suspension wires, cable tendons and optical cables. The optical cables include reinforcing cores, optical fibers, and protective layers. , it is difficult to connect the bifurcation of the optical fiber

In addition, most of the existing optical cables have a uniform color. Therefore, when multiple optical cables are laid on the same pole, there is a problem that they are not easy to be identified. During the day, the direction of the cables can be seen at a glance, but at night, if there is inspection or emergency repair, it will cause search. Difficult, causing a lot of inconvenience to power repair
