Stranded Loose Tube Single-steel-wire Armored Fiber Optical Cable


    The fibers, 250μm, 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 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. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is filling with the filling compound to protect it from water ingress. Then the cable covered is covered with a thin PE inner sheath. And a PSP is longitudinally applied over the inner sheath, the cable is covered with a PE outer sheath.  After the single-steel armored, the cable is finallycompleted with an outer sheath.
