24 Core Loose Tube Fiber Optic Cable Double Sheathed Fiber Optic Internet Cable
Cable Description
The fibers, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. FRP, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a non-metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the filling compound to protect it from water ingress, over which a thin PE inner sheath is applied. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.
Application
1. Adopted to ourdoor distribution;
2. Suitable for aerial, duct and direct buried;
3. Long distance and local area network communication.
Characteristics
1. Good mechanical and temperature performance
2. High strength loose tube that is hydrolysis resistant
3. Special tube filling compound ensure a critical protection of fiber
4. Crush resistance and flexibility
5. The following measures are taken to ensure the cable watertight:
6. Steel wire used as the central strength member
7. Loose tube filling compound and 100% cable core filling
8. APL moisture barrier
9. PSP enhancing moisture-proof
10. Water-blocking material
