Small-outer-diameter optical cable structure

Abstract

The invention discloses a small-outer-diameter optical cable structure, and relates to the technical field of optical cables, the small-outer-diameter optical cable structure comprises a body, the body comprises an outer sheath, the inner side of the outer sheath is provided with a plurality of special-shaped subunits and a reinforcing member, accommodating cavities are arranged in the special-shaped subunits, a plurality of optical fibers are arranged in the accommodating cavities, the manufacturing method of the special-shaped subunits is UV resin curing, the multiple special-shaped subunits are distributed in an array mode with the reinforcing member as the circle center, and the adjacent special-shaped subunits wrap the reinforcing member in an S-stranding mode. According to the invention, by using the special-shaped subunits, the outer diameter of the optical cable is reduced so as to reduce the production cost, the special-shaped subunits with different core numbers can be manufactured, the application range is expanded, and the optical cable structure is more compact and stable, so that the optical cable structure has the effects of energy conservation, environmental protection and better practicability.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to a small outer diameter optical cable structure. Background technique [0002] As the carrier of the communication industry, optical cable has developed particularly rapidly. [0003] At present, the existing optical cable structure often has a loose sleeve on the surface of the optical fiber. Because there is space between the loose sleeve and the optical fiber, the loose sleeve is usually large, wasting excess space resources, and when the loose sleeve is connected to multiple strength members There is a large gap, which virtually increases the production cost, resulting in poor practicability of the existing optical cable structure. Contents of the invention [0004] The purpose of the present invention is to provide a small outer-diameter optical cable structure, which can reduce the outer diameter of the optical cable to reduce production costs by using subunits wit...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a small outer-diameter optical cable structure, which has reduced the outer diameter of the optical cable to reduce production costs by using subunits with special-shaped structures, and can manufacture special-shaped subunits with different core numbers, which improves the The scope of application, as well as the tighter and more stable optical cable structure, make this optical cable structure have better energy-saving, environmental protection and practical effects, and solve the problem of the existing optical cable structure, which often has a loose sleeve on the surface of the optical fiber. It is necessary to leave space, so the loose sleeve is usually large, wasting excess space resources, and there is a large gap when the loose sleeve is connected to multiple strength members, which virtually increases the production cost and makes the existing optical cable structure practical. bad question
