GYFTZY Loose Tube Layer Stranded Non-metallic Reinforced Core 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. A  flame-retardant sheath is extruded over the cable core.


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. 

◆ Single non-metallic center strength member. 

◆ Possesses good mechanical performance and  temperature characteristics.


Application: Ducts, Aerial
