Loose Tube Stranded Armored Outdoor Fiber Optical Cable GYTY53

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.
The cable core is filled with the filling compound to protect it from water ingress,
over which a thin PE inner sheath is applied. After the PSP is longitudinally applied
over the inner sheath, the cable is completed with a PE outer sheath.
