Easy-to-strip layer stranded high-density fiber bundle air-blowing micro-cable

Abstract

The invention discloses an easy-to-strip layer stranded high-density fiber bundle air-blowing micro-cable. The micro-cable comprises a central reinforcing piece,and a loose sleeve and a filling rope are stranded on the outer surface of the central reinforcing piece; an optical fiber unit and a first water blocking substance are arranged in the loose sleeve,and the optical fiber unit is a fiber bundle; the first water blocking substance is water blocking fiber paste,and a second water blocking substance is further stranded on the outer surface of the central reinforcing piece; a water blockingstrip wraps the outer surface of the stranded loose sleeve and the filling rope,and the surface of the water blocking strip is coated with a sheath; a tearing rope is further arranged between the water blocking strip and the sheath,and the loose sleeve is made of TPEE. According to the micro-cable,an optical fiber can be stripped from the loose sleeve through a fingernail with bare hand,the effectof fast construction is achieved,and damage to the optical fiber is avoided.

Description

technical field [0001] The invention relates to the field of optical cable preparation, in particular to an air-blown micro-cable with layer-twisted high-density optical fiber bundles that is easy to peel off. Background technique [0002] With the continuous growth of information demand and the continuous advancement of the city's "optical traffic beautification" and "overhead landing" policies, the upgrade and expansion of optical fiber networks are also being carried out simultaneously. The pipeline resources for laying optical cables are becoming more and more scarce. Laying larger-capacity optical fibers is one of the key concerns of operators during network construction. Air-blown micro-cables are widely praised by customers for their high utilization rate of pipeline resources, good protection for optical cables, phased investment, short construction period, easy later upgrades and flexible branches. [0003] In large-scale use, due to the connection between optical ...

AI Technical Summary

Problems solved by technology

[0003] In large-scale use, due to the connection between optical cables and optical cables, the optical fibers are quickly fused to achieve the conduction effect, while in the fusion splicing, the optical fibers need to be exposed, and a stripping tool is generally used, but there is a problem of damage to the optical fibers due to improper operation, which affects Subsequent use
