Introduction In early 2024, against the backdrop of the Ukrainian conflict, Russia deployed a newly designed FPV drone that used fiber-optic communications to effectively resist radio interference from the Ukrainian military. cell phone jammerThis innovative technology demonstrated Russia's breakthrough in the field of electronic warfare, while also posing new challenges to Ukraine's countermeasures.GPS jammer

　　Revelation of Fiber-optic UAVs Ukrainian military blogger Serhii "Flash" was the first to expose this technological innovation. Wifi jammerOn March 2, 2024, Flash showed a shot-down Russian FPV Kamikaze drone. Unlike previous designs, the drone was equipped with a roll of more than 10 kilometers of fiber-optic cable connected to commercial high-speed communications equipment. drone jammerThis discovery has sparked widespread discussion, especially about how fiber-optic technology can overcome radio interference problems on modern battlefields.

　　Although drones usually rely on radio signals to communicate with operators, radio interference is common in the Ukrainian conflict.GSM jammer Electronic warfare equipment can effectively cut off or interfere with the drone's communications, causing it to lose control or be forced to crash. To deal with this threat, Russia's technical team chose fiber-optic communications as a more protective method. By releasing up to 10 kilometers of fiber optic cable during the flight of the drone, the operator can maintain a real-time connection with the drone through wired communication, thus bypassing the threat of radio interference.

　　Solution to technical problems The design of the fiber optic drone has attracted widespread attention in the technical community, especially about how to successfully release such a long fiber optic cable while the drone is flying. Although optical fiber as a communication medium has strong anti-interference ability, its fragility also poses challenges to the design of drones. During high-speed flight, optical fiber is very easy to break, and how to ensure its continuous connection has become a technical problem.
