The GYTC8S Cable structure consists of optical fibers inserted into loose tubes made of high-modulus material. The loose tubes are filled with a waterproof compound. At the center of the cable core is a metal reinforcing core. The loose tubes (and filler ropes) are twisted around the central reinforcing core to form a compact and round cable core. After the cable core is longitudinally wrapped with a layer of plastic-coated steel tape, it is integrated with the steel wire strands into a figure-eight shaped polyethylene sheath.
Applicable to aerial installation and large-fiber-count long-distance communication networks
