GYXTS is a steel-reinforced, polyethylene-sheathed outdoor fiber optic cable designed for duct and conduit installations. It features a robust structure with central loose tube fiber units and corrugated steel tape armor, making it ideal for long-distance communication, service drops, and building. GYXTS cable structure is to insert a single or multimode fiber loose tube,made of high modulus plastic it external wire winding layers of double-sided plastic corrugated steel belt longitudinal packaging, as well as the extrusion of PE fiber optic cable outer sheath formation. Loose tube for external use is a layer of steel wire armor layer longitudinally wrapped, with water blocking.
