48 Fibers Single Mode Outdoor Optical Fiber Cable GYTA53 with Double Sheath
1. 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. A steel wire, 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 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.
2.Application
· Adopted to ourdoor distribution;
· Suitable for aerial, duct and direct buried;
· Long distance and local area network communication.
3. Characteristics
· 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
· 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
· APL moisture barrier
· PSP enhancing moisture-proof
· Water-blocking material
