Product Description:

Colored optical fibers are placed in a loose tube made of  high-modulus, water-resistant material. The loose tube is filled  with a non-toxic, harmless waterproof compound. At the center  of the cable core is a non-metallic reinforcing core(FRP), around  which the loose tube(or filling yarn)is twisted to form a  compact circular cable core. Outside the reinforcing core, there  is a water-blocking yarn, followed by extrusion of a black or  colored high-density polyethylene sheath to form the cable.

Product Feature:

◆ The use of non-metallic reinforcing elements results in a  small outer diameter, light weight, moderate flexibility, and a  low coefficient of friction for the outer sheath, allowing for  longer air-blowing distances. 

◆ Special oil paste is filled inside the loose tube to provide  cushioning protection for the optical fibers and to achieve  waterproof performance for the cable. 

◆ The tight cable structure effectively prevents tube shrinkage.
