Fiber Optic Reel — an Anti-EW Solution for Drones

In combat zones, radio channels often become vulnerable: they are easy to jam, intercept, or suppress. That’s why fiber optic reels for drones are increasingly used on the front line — a solution that ensures stable, radio-free communication. By transmitting signals through optical fiber, these systems allow UAVs to remain invisible to enemy EW systems and maintain full control even in the harshest conditions.

Use Cases: UAVs, UGVs, and USVs in Combat Conditions

Fiber optic reels are widely used in military unmanned technologies, where stable and secure communication channels are mission-critical.

Most common applications:

• FPV drones — for strike or intelligence missions with a high risk of signal jamming;
• heavy quadcopters & multicopters — for long-distance video and telemetry transmission or use in complex environments;
• unmanned ground vehicles (UGVs) — for assault, engineering, or intelligence operations in open terrain, dense urban areas, basements, or tunnels;
• operations under active EW pressure — where radio communication fails or is at risk of interception;
• short-range missions where stealth and delay-free control are essential.

Where radio communication is blocked or suppressed, the fiber optic reel ensures stable transmission of control commands, telemetry, and video via fiber without delays, losses, or radio emissions.

Advantages of the Fiber Optic Module: Technology and Implementation

The fiber optic module ensures communication without radio emissions, making it resistant to EW, interception, and jamming. Thanks to a direct physical channel, communication via fiber is free from delays, interference, and quality loss — which is crucial for real-time control and provides even better video transmission than radio links.

We develop our fiber optic modules in Ukraine, focusing on real combat conditions and the needs of the Ukrainian Armed Forces. Each module features:

• a minimum bend radius of 7.5 mm — for compact winding without damage;
• support for S-BUS, CRSF, and Ethernet protocols — for universal integration;
• power input from 5 to 30 V — compatible with most modern platforms;
• mechanical mounting via bracket — for quick integration into drone or ground vehicle frames;
• ergonomic housing and fiber protection — minimizing the risk of damage under combat conditions.

In real-world use, the module demonstrates vibration resistance, reliable performance at altitudes up to 500 meters and speeds up to 70 km/h, delivering stable control and video transmission even in dynamic scenarios.

Fiber Length and Module Applications

We offer reels with varying fiber lengths for different types of unmanned platforms:

• 2–12 km — ideal for drones with 10" frames and larger, suited for mid-range missions with high signal quality;
• 15–20 km — designed for larger drones (13" and up) requiring extended range for complex combat tasks.

Who Uses the Fiber Optic Module and Why BTRY.ENERGY

BTRY ENERGY fiber optic modules are made for combat operations — where any loss of signal can be critical. Our products are designed for:

• FPV drone crews;
• UGV operators;
• unmanned surface vehicle (USV) units;
• intelligence and strike teams operating in high EW activity areas;
• engineers developing high-precision unmanned systems with reliable control links.

We understand that a fiber optic reel is not just a component, but a mission-critical part of communication. That’s why:

• every module is developed and assembled in Ukraine;
• only industrial-grade fiber, precise winding, and quality connectors are used;
• we provide technical support and assist in configuration selection;
• we work openly with requests for specialized use cases — from short raids to full-scale offensive missions.

By choosing BTRY ENERGY, you receive not just a device, but a core element of the system keeping your drone or UGV connected.
