Flat-type multi-cavity branched optical cable and manufacturing method thereof

Abstract

The invention relates to a flat-type multi-cavity branched optical cable and a manufacturing method thereof. The flat-type multi-cavity branched optical cable comprises an external protecting bush and optical fibers, wherein the external protecting bush sleeves the optical fibers. The flat-type multi-cavity branched optical cable is characterized in that the external protecting bush is flat and 2-4 hollow pipes which are arrayed in parallel are formed in the middle of the flat external protecting bush; the hollow pipes loosely sleeve the optical fibers; reinforcing parts are mounted on two sides in the flat external protecting bush respectively. The flat-type multi-cavity branched optical cable is easy to strip and branch from a flat side, is easy to bend and has high compression resistance; the protecting bush is made of the hollow pipes and a low friction coefficient material; the optical fibers and the hollow pipes have a relatively large duty ratio; the optical fibers needing to be branched can be extracted and branched from the protecting bush in a relatively long distance and the residual optical fibers can be continuously laid frontward along the cable and the laying efficiency of the optical cable is improved; the two reinforcing parts are arranged and an outer layer of the external protecting bush is a hard high density polyethylene layer, so that the optical cable has relatively great tensile resistance and compression resistance; the flat type multi-cavity branched optical cable is simple and reasonable in structure; the protecting bush can be molded in one step; the flat-type multi-cavity branched optical cable is low in manufacturing cost and light in weight and is easy to branch and lay.

Description

technical field [0001] The invention relates to a flat multi-cavity branch optical cable and a manufacturing method thereof. Background technique [0002] In the context of Internet+, there will be a rapid demand for outdoor optical fiber cables. At present, the commonly used methods in China are aerial access to households with leather cables or ordinary GYTA / S optical cables. Difficult, especially when each household needs 1 to 2 optical fibers to enter the home, other optical fibers need to be interrupted for branch fusion, which is costly and inefficient. The laying of branches was inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flat multi-cavity branch optical cable and its manufacturing method for the shortcomings of the above-mentioned prior art. The optical cable not only has a simple structure, a large fiber capacity, is easy to branch and lay, and has good mechanical properties. [000...
