Description: The fibers, 250μm,
are positioned in a loose tube made of a high modulus plastic. The tubes are
filled with a waterresistant 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. 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. After the PSP is longitudinally applied
over the inner sheath, the cable is completed with a PE outer sheath.
