The fibers, 250μm, single mode or muti mode , 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.
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.
