Fiber optics is a cable for transmitting data using a light signal through thin glass or polymer fibers. For drones, this technology provides stable communication, high data transfer speed, and less dependence on radio interference. An additional advantage can be a higher quality video signal and a lower probability of losing the control channel in difficult conditions.
A fiber optic reel for a drone is a module with a wound cable that gradually unwinds as the platform moves. Such a system provides a physical connection between the drone and the control point for signal and data transmission. The cable length, reel weight, and mechanism design depend on the drone class and specific purpose.
The weight of fiber optic spools typically ranges from 0.5 to 5 kg, depending on cable length and system housing. Lighter modules have less impact on maneuverability and flight time, while heavier options increase the load on the motors. With increasing weight, climb rate, autonomy, and overall flight dynamics usually decrease.
The cable length in fiber optic reels typically ranges from 1 to 20 km, depending on the system type and task. Shorter solutions up to 5 km are more often used for compact platforms, while larger cable reserves may be applied for specialized systems. The actual operating distance also depends on the flight path and terrain conditions.
Fiber optic reels are most often used with FPV drones, tactical quadcopters, and specialized medium-class platforms. These are usually models with a frame diagonal of 7 to 13 inches, or larger cargo solutions. Specific compatibility depends on the drone's payload capacity, thrust reserve, and reel mounting design.
Signal transmission via fiber optics is typically characterized by high speed, low latency, and resistance to electromagnetic interference. This allows for stable transmission of video, telemetry, and control commands over significant distances. Performance quality may vary depending on cable integrity, equipment, and system settings.
The main limitations are the additional weight, mechanical resistance of the cable, and the risk of line damage during flight. In complex terrain or among obstacles, the cable can snag on objects, affecting maneuverability. Also, as the coil length increases, the system's dimensions and platform load typically grow.
The cost of fiber optic reels for drones in Ukraine typically starts from approximately UAH 20,000–40,000 for basic solutions and can exceed UAH 80,000–200,000 for professional configurations. Price is influenced by cable length, housing type, unwinding mechanism, and platform compatibility.
