For field communication and industrial UAV applications, buyers usually focus on tensile performance, bend radius, attenuation stability and reel design before bulk procurement. This product is built around exactly those points.
Product Details
This product is a G657A2 bend-insensitive bare fiber, 200/242μm, wound on a 3D-printed ABS reel and built for long-range FPV drone and UAV field communication links. The internal wiring design keeps the fiber protected inside the housing during dynamic release, which reduces the friction points that cause fiber breakage in flight.
It is supplied for drone manufacturers, FPV system integrators and fiber processing buyers in Europe and North America who need a stable, high-tensile fiber that pays out smoothly during fast and variable-speed operations. Reel design, fiber length and coating options are matched to your drone platform.
Compliance note: We only discuss fiber communication material performance and export-compliant industrial / field communication applications. We do not provide weaponization, targeting or tactical deployment advice.
The fiber is G657A2 with a minimum bend radius of around 7.5mm, tighter than G657A1 (around 10mm). This bend performance lets the fiber be wound and released inside a compact reel without large attenuation penalties during sharp internal routing.
Drone fiber fails most often during dynamic release, not at rest. The standard version supports around 50N tensile strength, with enhanced or customized versions available up to 55–60N. Based on field trial feedback from similar long-range applications, a controlled-tensile A2 fiber improves unwinding stability compared with standard telecom fiber.
The 200/242μm coating is thinner than standard 245μm fiber, so more fiber fits on a reel at lower weight. For airborne platforms where every gram affects flight time and range, the reduced diameter directly supports longer winding length without adding payload.
Typical attenuation is around ≤0.35 dB/km at 1310nm and ≤0.22 dB/km at 1550nm. Low and consistent attenuation is what supports clear, stable signal transmission over long unwinding distances, rather than relying on a single marketing distance figure.
The internal wiring approach secures the fiber inside the housing and at the ground end, which helps prevent loosening and displacement during takeoff, landing and high-speed maneuvers. This lowers the practical break risk across repeated missions.
The bare fiber is supplied through deep inventory and distribution partnerships with major Chinese fiber brands — YOFC, Hengtong, ZTT and Fiberhome. This supports consistent fiber geometry and attenuation across repeat orders for buyers producing drone fiber reels in volume.
For drone bare fiber, batch reliability matters more than a one-time low price. Depending on the order, testing can include OTDR testing, attenuation verification and per-reel test reports, so each reel entering your production or deployment is checked before shipment.
Because the fiber is sourced from major-brand inventory with controlled cladding quality, fiber geometry and attenuation stay consistent across reels. For buyers who cannot inspect in person, factory video inspection and per-reel test records can be provided.
