The structure of GYTC8S optical cable is to put 250um optical fiber into a loose tube made of high modulus material, and the loose tube is filled with waterproof compound. The center of the cable core is a metal reinforcing core, loose tubes (and filling ropes) are twisted around the central reinforcing core to form a compact and circular cable core, and the cable core is longitudinally wrapped with a layer of plastic-coated steel strip (PSP), and steel wire The stranded wires are integrated into a figure-eight polyethylene sheath.
