Description
The fibers, single mode or muti 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.
Standards
The GYXTA cable is compliant with the YD/T 1114 standard.
Features
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 used as the central strength member
Loose tube filling compound and 100% cable core filling
Aluminum tape enhancing moisture-proof
Application
Adopted to outdoor distribution;
Suitable for aerial, pipeline laying method;
Long distance and local area network communication.
