GYHTY Loose Tube Layer Stranded Non-metallic Reinforced Core Optical Cable

Product Description:

Colored optical fibers are placed into a loose tube made of  high modulus material, which is then filled with thixotropic  water-blocking gel. The center of the cable core contains a  glass fiber reinforced plastic(FRP). The loose tube(and  filling rope)is twisted around the central reinforcing core to  form a circular cable core. Gaps in the cable core are filled  with water-blocking gel, and then extruded with a  polyethylene inner sheath. This is followed by an outer  sheath made of aramid yarn, extruded with polyethylene  to complete the cable.


Product Feature:

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

◆Possesses good mechanical performance and  temperature characteristics. 

◆Aramid reinforcing elements enhance the cable's  tensile strength. 

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

◆PE sheath has excellent resistance to ultraviolet  radiation. 

◆Single non-metallic central reinforcing core.


Application: Ducts, Aerial, Direct Burial
