GYTA53+33 Outdoor Fiber Optic Cable Double Steel Layer Underwater Armored Submarine Cable

Description

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 filled with the filling compound to protect it from water ingress. Then the cable core 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 finally completed with an outer sheath.
