5km Fiber Optic Tether Spool for UAV & FPV Drones

5KM Fiber Optic Spool for Tactical UAV Operations

The 5KM Fiber Optic Spool is designed for mid-range UAV missions where stable and interference-free communication is required. It provides a secure optical data link for surveillance, inspection, and field-deployable drone systems.

Unlike long-endurance 20KM systems, the 5KM configuration focuses on balanced range and portability. Therefore, it is ideal for mobile ground teams, temporary monitoring setups, and compact UAV platforms.

range developed for defense, research, and industrial drone communication.

Stable Transmission with G657A2 Single-Mode Fiber

The system uses G657A2 single-mode fiber optimized for 1310nm and 1550nm wavelengths. Because of its low attenuation characteristics, signal strength remains consistent across the full 5KM range.

In addition, optical transmission eliminates RF interference, ensuring reliable telemetry, command signals, and live video feeds in restricted or high-interference environments.

Compact and Field-Ready Construction

The reinforced ABS housing protects the fiber during deployment, while the precision-machined aluminium exit nozzle minimizes abrasion and micro-bending. As a result, fiber release remains smooth throughout continuous tethered drone operations.

Its balanced weight makes it suitable for mobile ground units and rapid deployment scenarios.
