50.4KM G657A2 Bare Optical Fiber Ultra-Bend Insensitive UAV & FTTH Optimized
G.657.A2 Bare Optical Fiber: Ultra-Bend Insensitive Solution for Compact & Dynamic Applications
Our G.657.A2 Bare Optical Fiber is a high-performance, bend-insensitive singlemode fiber (BIF) engineered to redefine the limits of optical connectivity. Featuring a specialized refractive index profile, this fiber maintains optical integrity even at an ultra-tight 7.5mm bending radius.
While standard G.652.D fiber suffers from significant signal loss when coiled or turned sharply, the G.657.A2 fiber is optimized for space-constrained environments. It serves as the essential core component for applications ranging from discreet indoor FTTH (Fiber to the Home) drop cables to advanced, high-tensile UAV (Unmanned Aerial Vehicle) tether systems, where fibers must endure rapid spooling and extreme bending under tension.
Key Performance Advantages
- Ultra-Low Bending Loss: Minimal macro-bending attenuation (R = 7.5mm), ideal for tight enclosures, wall corners, and rapid deployment spools
- UAV & Defense Optimized: Available with enhanced coatings (polyimide or high-tensile acrylate) designed for extreme mechanical demands of fiber-guided drones and tethered aerostats
- Full Backwards Compatibility: Fully compatible with existing G.652.D networks for seamless splicing and integration
- Low Attenuation & Zero Water Peak: Stable performance across the entire 1260nm to 1625nm wavelength range
- High Mechanical Reliability: Dual-layer UV-curable acrylate coating provides superior micro-bending protection and long-term fatigue resistance

Targeted Application Scenarios
The G.657.A2 fiber is the designated choice for modern high-performance hardware:
- UAV (Drone) Tether & Guidance Systems: Essential for tethered drones requiring continuous power and data. The fiber's extreme flexibility allows tight spooling and rapid deployment under tension without signal loss, critical for FPV (First-Person View) and sensor data backhaul in defense and industrial monitoring
- FTTH Drop Cables & Indoor Wiring: Preferred fiber for residential and office deployments where cables must navigate sharp baseboard corners and staples without macro-bending attenuation
- MPO/MTP High-Density Patching: Ideal for compact data center hardware where cable management space is at a premium
- Medical & Industrial Sensors: Used in small-form-factor medical probes and industrial robotic arms requiring ruggedized, flexible fiber links
