GYDTA Loose Tube Layer Stranded Non-armored 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 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  a coated aluminum 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 coated aluminum tape provides


Application: Ducts, Aerial
