Loose Tube Stranded Armored Outdoor Fiber Optical Cable GYTA53

The fibers, 200/250μm, 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. 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.
