Stranded Loose Tube Light-Armored Fiber Optic Cable CYTS

The fibres, 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, sometimes sheathed with polyethene (PE) for cable with high fiber count, locates in the center of the core as a metallic 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.
