1 Core G657A2 Outdoor Drop Cable 3 Steel Wire With Messenger
The 1 Core Outdoor Drop Cable with a 3 steel wire structure is an ultra-reliable, high-tensile fiber optic cable engineered for FTTH (Fiber to the Home) last-mile aerial access networks. This cable houses a single premium G.657.A2 bend-insensitive single-mode fiber core, allowing for tight bend radiuses along outdoor walls and inside terminal boxes without any signal degradation.
Built to withstand heavy outdoor weathering, the cable features a 3-wire reinforcement design: two parallel steel wires flank the internal optical tube for superior crush resistance, while a heavy-duty outer self-supporting messenger wire absorbs overhead pulling strain. For maximum project flexibility, the messenger wire can be customized with either Phosphated Steel Wire (high fatigue resistance) or Galvanized Steel Wire (superior anti-corrosion for humid or coastal environments).
- Premium G.657.A2 Fiber: Outstanding bend-insensitive performance, perfect for rugged outdoor-to-indoor transition routing.
- Robust 3 Steel Wire Structure: Dual parallel wires plus the top messenger wire provide a rock-solid mechanical framework against wind and ice.
- Customizable Messenger Wire: Choose Galvanized steel for enhanced rust protection or Phosphated steel for high tensile reliability based on your local climate.
- Self-Supporting Aerial Deployment: Designed specifically for overhead pole-to-house installations, eliminating the need for a separate support cable.
- Weather-Resistant Jacket: Wrapped in an industrial-grade, UV-resistant black LSZH or PE sheath that prevents cracking under sun and rain.
