The G657A2 single-mode optical fiber is specially designed for applications requiring high bend resistance and flexibility, making it ideal for FPV (First-Person View) drone signal transmission. It maintains stable optical performance even in extremely tight spaces and sharp bends, ensuring uninterrupted, high-speed data flow. This fiber complies with ITU-T G.657.A2 standards and is widely used in lightweight, miniaturized aerial communication systems.
