Stranded Loose Tube Armored Fiber Optic 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 wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The PSP is longitudinally applied over the cable core, which is filled with the filling compound to protect it from water ingress. The cable is completed with a PE sheath.
