Stranded Loose Tube Light Armored Cable – GYFTA
The 250um bare fibers 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. An aluminum
polyethylene Laminate (APL) is applied over the cable core, which is filled with the filling compound to
protect it from water ingress. Then the cable is completed with a PE sheath.
