Stranded Loose Tube Non-armored Cable GYTA

Description


 

The fibers, single-mode or multi-mode, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A Aluminum tape, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The Aluminum tape is longitudinally applied over the cable core, which is filled with the filling compound to protect it from water ingress. The cable is completed with a PE sheath.

 

Characteristis



 

•  Good mechanical and temperature performance
•  High strength loose tube that is hydrolysis resistant
•  Special tube filling compound ensure a critical protection of fiber
•  Crush resistance and flexibility. PE sheath protects cable from ultraviolet radiation
•  The following measures are taken to ensure the cable watertight:
     Steel wire is used as the central strength member
     Loose tube filling compound and 100% cable core ling
     Aluminum tape enhances moisture-proof
