GYTZS Loose Tube Layer Stranded Flame-retardant Optical Cable

Product Description:

Colored optical fibers are placed in a loose tube made of  high-modulus material, filled with thixotropic gel. The center of the  cable core is a metal strength member. The loose tube(and filling  rope)is twisted around the central strength member to form a  circular cable core, with the interstices of the cable core filled with  water-blocking gel. The cable is sheathed with a flame-retardant  material after being longitudinally wrapped with double-sided  corrugated steel tape.


Product Feature:

The material of the loose tube itself has good resistance to  hydrolysis and high strength. 

◆ Filled with thixotropic gel inside the tube, providing crucial  sealing protection to the optical fibers.  

◆ Special sheath material has excellent flame retardancy. 

◆ A single steel wire central strength member contributes to the  parallelism and tensile strength of the optical cable. 

◆ Possesses good mechanical performance and temperature  characteristics. 

◆ Coating with double-sided corrugated steel tape (PSP) enhances  the cable's resistance to moisture ingress


Application: Aerial
