Abstract

The invention provides a braided network tube coated multi-core optical cable, which comprises a cable core and a braided network tube coated outside the cable core, and is characterized in that the cable core is formed by twisting a plurality of unit cables, and the minimum twisting diameter of the cable core is the theoretical twisting outer diameter of the plurality of unit cables; the folding diameter of the woven net pipe is smaller than or equal to the twisting outer diameter of the cable core, and the difference value between the outer diameter of the woven net pipe and the twisting outer diameter of the cable core is not larger than 1 mm. The invention further provides manufacturing equipment of the woven mesh tube coated multi-core optical cable. The optical cable has the advantages of being small in size, light in weight, large in core number, compact in structure, flexible, easy to bend, low in sheath shrinkage and extension and the like, is suitable for indoor comprehensive wiring, and can meet the high-density network wiring connection requirement of a data center.

Description

technical field [0001] The application relates to the field of optical cable manufacturing, in particular to a multi-core optical cable covered with a braided network pipe and its manufacturing equipment. Background technique [0002] At present, the existing small-core indoor multi-core optical cable generally adopts a non-bundled optical cable structure, which is composed of multiple coated optical fibers, multiple tight-buffered optical fibers, multiple single-core loose-tube optical fibers, multi-core loose-tube optical fibers, or optical fiber bundles. Core, non-bundled optical cable consists of a cable core, a strengthening member and a sheath. The existing large-core indoor multi-core optical cable generally adopts a bundled optical cable structure, with a single sheathed non-bundled optical cable as a sub-cable, and multiple sub-cables and possible filling ropes are twisted into a layer or multi-layer structure to form a clustered optical cable core. Core center str...
