We insert single-mode or multi-mode into loose tube made of high modulus polyester material and filled with water proof compounds. The center of cable core is a metallic strength core. For the cables with a certain number of cores, the metallic strength core sheathed with polyethylene (PE). The loose tube (and filling rope) is twisted around the central strength core to form a compact circular core, whose cracks are filled with water blocking materials. Extruded polyethylene sheath into cable after the double chromium-plated plastic steel tape vertical wrapped. Finally, extruded polyethylene sheath into cable after armored of single steel wire.
