Description:
The fibers are placed in a loose tube made of high modulus plastic.  The tubes are filled with a water-resistant filling compound.  A steel wire locates in the center of core as a metallic strength member.   The tubes (and fillers) are stranded around the strength member into a compact and circular cable core.   After PSP is applied around the cable core,  thisart of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene(PE) sheath to be figure 8 structure.

Features:
Accurate fiber excess length ensures a good performance of tensile strength and temperature.
High strength loose tube that is hydrolysis resistant and special tube filling compound ensure a critical protection of fiber.
High tensile strength of stranded wires meet the requirement of self-supporting and reduce the installation cost.
The following measures are taken to ensure the cable watertight:
        – Single steel wire as the central strength member
        – Loose tuble filling compound
        – 100% cable core filling
        – PSP enhancing moisture-proof
