Underground optical cable sheathing
LSZH: used where the cable enters buildings or tunnels with strict fire and smoke limits. Dual-sheath designs: PE + LSZH or PE + PE for extra mechanical and chemical protection. Steel tape armored (STA): good radial compression resistance, widely used under sidewalks and verges. In the digital age, underground fiber optic cable serve as the invisible arteries of global communication, enabling gigabit connectivity for urban centers, industrial complexes, and smart communities. As a leading manufacturer of end-to-end fiber optic solutions, Weunion specializes in engineering. The fibers, 250µm, are positioned in a loose tube made of a high modulus plastic. Match trench method with the correct underground fiber structure (GYTS, GYTA53, GYTY53, micro-duct).
