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 (may PE blanket) locates in the center of core as a metallic strength member. Tubes are stranded around the strength member into a compact and circular cable core. An steel Polyethylene Laminate（PSP） is applied around the cable core, which is filled with the filling compound to protect it from water ingress. Then, the cable is completed with a PE sheath. After the single-steel wire armored, the cable is finally completed with an outer sheath.
