GYTS 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, sometimes sheathed with polyethylene (PE) for cable with high fiber count, 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 which is filled with the filling compound to protect it from water ingress.After the PSP is longitudinally applied over the cable core, the cable is completed with a PE outer sheath.
