The GYXTS optical cable structure is a loose tube made of high modulus polyester material with single-mode fiber or multi-mode fiber, and the tube is filled with waterproof compound. The loose tube is provided with water-blocking material to ensure the longitudinal water seepage of the optical cable. After the steel wire is wrapped into the cable, the double-sided chrome-plated plastic-coated steel tape (PSP) is longitudinally wrapped, and then the polyethylene sheath is extruded.
