In the GYTA53 cable, single-mode/multimode fiber are positioned in the loose tubes, which are made of high modulus plastic materials, while the loose tubes strand together around metallic central strength member into a compact and circular cable core. For certain high fiber count cables, the strength member would be covered with polyethylene (PE). The water-blocking materials are distributed into interstices of the cable core, and the Aluminum Polyethylene Laminate (APL) is longitudinally applied around the cable core before a PE sheath is extruded over it, then corrugated steel tape and outer sheath are applied finally.
