Central Tube Figure-8 Self-Supporting Aerial Cable (ADSS)

GYFXTC8F

The GYFXTC8F optical cable structure involves placing 250μm optical fibers into a loose tube made of high-modulus material, with the tube filled with waterproof compound. The loose tube is longitudinally wrapped with a layer of non-metallic tape, then integrated with a non-metallic reinforcement member into a figure-8 polyethylene sheath.
