■ Description:

The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tube 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. Then, the cable is completed with a Blue Flame Retardant Jacket.

■ 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.

• Two parallel steel wires ensure tensile strength

• Small diameter, light weight and friendly installation

• Long delivery length

• Application:duct/aerial
