GYTC8A 8-Shaped Self-Supporting Fiber Optic Cable

Product Description:

Colored optical fibers are placed into a loose tube made of  high-modulus, hydrolysis-resistant material, which is filled  with thixotropic water-blocking gel. The core of the cable  consists of a central metal strength member, around which  the loose tube(and filling rope)is twisted to form a compact  and circular cable core. The cable core is longitudinally  wrapped with a layer of coated aluminum tape and  integrated with steel strand wires into an 8-shaped  polyethylene sheath.


Product Feature:

◆ Exhibits good mechanical performance and temperature  characteristics. 

◆ The steel strand wire serves as a self-supporting element to  meet the tensile strength required for aerial  installation,reducing installation costs. 

◆ The material of the loose tube has good hydrolysis  resistance and excellent pressure resistance.

◆ Filled with special grease inside the tube,providing crucial  protection for the optical fibers. 

◆ Double-sided coated steel tape enhances the cable's  resistance to moisture penetration.


Application: Aerial
