AI Technical Summary

Technical Problem

When existing air-blowed optical cables enter the external pipe, the contact area between the outer sheath and the pipe is large, resulting in high friction and increasing the difficulty of construction and layout.

Method used

An air-blowing optical cable with a boost structure is designed, using non-metal reinforcements and a high-density polyethylene outer sheath, and multiple quarter-sphere-shaped depressions are provided on the surface of the outer sheath to reduce friction and wind resistance, improve air-blow distance and installation flexibility.

Benefits of technology

It effectively reduces the friction and air resistance of the optical cable, improves the air blowing distance and installation flexibility, reduces the difficulty of construction and layout, and improves the durability and service life of the optical cable.
