GYXTW Cable Structure:
250μm optical fibers are housed in a high-modulus loose tube filled with waterproof compound. The tube is longitudinally wrapped with double-sided plastic-coated steel tape (PSP), with water-blocking material between the tape and tube for compactness and longitudinal water resistance. Two parallel steel wires are embedded on both sides, and the assembly is sheathed with polyethylene to form the cable.
