G657A2 0.25mm 50.4km/reel Single Mode Optical Fiber: Revolutionizing Drone Communication & Testing

As drone technology evolves from recreational use to mission-critical applications in defense, industrial inspection, and aerial cinematography, the demand for reliable, high-performance communication links has never been greater. GL-FIBER introduces its breakthrough G657A2 0.25mm single-mode optical fiber—a ultra-thin, high-strength solution engineered specifically for long-range, interference-free drone operations and rigorous testing environments.

Why Choose Our 0.25mm G657A2 Single Mode Optical Fiber?

1. Ultra-Thin, High-Flexibility Design

0.25mm Diameter: Lighter than a human hair, enabling seamless integration into micro drone gimbals and compact FPV systems.

Bend-Insensitive Performance: Compliant with ITU-T G657.A2 standards, supporting a minimum bend radius of 7.5mm with near-zero signal loss.

2. Extended Transmission Capabilities

50km Uninterrupted HD Video: Achieves ≤0.22 dB/km attenuation at 1550nm, supporting real-time 1080P/4K video feeds for beyond-visual-line-of-sight (BVLOS) operations.

Full O-to-L Band Compatibility: Optimized for 1260–1625nm wavelengths, ideal for DWDM/CWDM systems in 5G-connected drone networks.

3. Military-Grade Durability

500N Tensile Strength: Aramid-reinforced fiber withstands high-speed drone maneuvers and extreme environmental stress.

-40°C to +85°C Operating Range: Reliable performance in Arctic surveys, desert surveillance, or tropical storms.
