GYTZA Loose Tube Layer Stranded Non-armored 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 then extruded with  a flame-retardant sheath after longitudinally wrapping with  coated aluminum tape.


Product Feature:

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

◆ Filling the tube with thixotropic gel provides critical sealing  

◆ 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. 

◆ Coated aluminum tape moisture-proof layer.


Application: Ducts, Aerial
