GYDTS Loose Tube Layer Stranded Lightweight Fiber Ribbon Optical Cable

Product Description:

4, 6, 8, 12-core fiber ribbon is 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 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. After longitudinal wrapping with  double-sided coated steel tape, the cable is extruded with a  polyethylene sheath.


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. Flexible application with 2, 6, 8, 12-core fiber ribbon. 

◆Possesses good mechanical performance and temperature  characteristics. 

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


Application: Ducts, Aerial
