Hengtong G.657.A2 50.4km Bare Optical Fiber Reel for FPV Drones (0.25mm)

Hengtong G.657.A2 single-mode bare optical fiber on an ultra-long 50.4km industrial master reel is a premium-grade hardware component engineered for winding onboard FPV drone spools and building reliable, high-bandwidth data links. In modern tactical scenarios, fiber-optic drone deployment offers total immunity against Electronic Warfare (EW/jamming) and eliminates the radio-frequency signature of the drone operator, maintaining complete signal stealth.

The fiber conforms to the ITU-T G.657.A2 classification, ensuring superior bend-insensitive characteristics with a minimum bend radius down to 7.5 mm. This mechanical flexibility allows the bare glass thread to tolerate sharp deflections, micro-bends, and structural tension during high-velocity payout from a fast-moving quadcopter without micro-fractures or optical signal drops. Featuring a ultra-thin outer coating diameter of 0.25mm (250µm), protected by a specialized high-performance composite acrylic resin, the fiber guarantees seamless high-speed deployment. Delivered as a continuous bare spool with clean ends ready for fusion splicing, this product is ideal for customization into mission-specific lengths (e.g., 10km, 20km segments). It delivers zero water peak attenuation and ultra-low control latency across O, C, and L telecommunication bands.
