View Product Description

Outdoor Steel Tape Armored Direct Buried Underground Fiber Cable GYTY53

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.

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
➢ 100% cable core filling
➢ PSP enhancing moisture-proof
➢ Water-blocking material

Application:

1. Adopted to outdoor distribution.
2. Suitable for aerial, duct and direct buried.
3. Long distance and local area network communication.
