Double-fly Outdoor Cable | Product Standards
The double-fly outdoor drop cable is designed for overhead and duct installation in FTTH networks. It uses bend-insensitive G.657.A2 fiber and dual parallel steel/FRP reinforcement for excellent tensile strength and compression resistance. The UV-resistant low-smoke halogen-free sheath complies with IEC 60754 (low smoke) and RoHS standards, ensuring durability in harsh environments while prioritizing safety and ease of deployment.
Double-fly Outdoor Cable | Product Standards
-
Fiber Core: 2×G.657.A1/B3 bend-insensitive fibers (single-mode, 9/125μm).
-
Reinforcement: Dual parallel FRP (Fiber Reinforced Plastic) or steel wires (optional: 0.5-1.0mm diameter) for crush resistance.
-
Sheath: LSZH (Low Smoke Zero Halogen) jacket, available in black or color-coded options, compliant with IEC 60332 flame-retardant standards.
