Media Converter 20/40/60/80/100 km
Compact two-component system (Air/Ground) for analog video and control signal transmission up to 60 km. The module is engineered for operation under complete radio silence and ensures zero signal latency. It achieves peak performance when paired with G657A2 single-mode fiber optic cable, which guarantees signal integrity even with tight cable bends during flight.

Why choose Media Converter 20/40/60/80/100 km
The fiber optic module from SkyCraft is designed to provide a reliable communication link between the operator and the UAV in environments where radio frequency usage is impossible. The system operates by converting electrical signals (video and telemetry) into light pulses transmitted through the cable’s glass core. This allows the system to completely ignore any hostile jammers and operate in full radio silence mode.
Key Features and Engineering Solutions
- Wavelength Division Multiplexing (WDM): The use of different wavelengths (1310 nm for the air unit and 1550 nm for the ground unit) enables simultaneous video transmission and control command reception over a single fiber without mutual interference.
- Connection Reliability: The module is equipped with an FC-type connector with threaded locking, which prevents accidental cable disconnection caused by motor vibrations or sharp drone maneuvers.
- Universal Power Supply: A wide input voltage range (5.5–26 V) allows the air module to be powered directly from the drone’s onboard power system (2S–6S) without the need for additional BECs.
- Flight Controller Integration: Full support for TTL signals and protocols like CRSF (Crossfire/ELRS) ensures easy setup of telemetry and control via standard UART ports.
Advantages Compared to Other Solutions
Unlike standard systems limited to 20-25 km, this module supports stable operation at distances up to 60 km (provided the appropriate fiber spool is used).
Since the signal is transmitted within a physical fiber optic cable, the drone becomes “invisible” to electronic intelligence (ELINT) and invulnerable to dome suppression systems.
With power consumption of only 5 W, the module has a minimal impact on total flight time, which is critical for long-range missions.
The built-in LED indication system allows the operator to quickly verify power status, video signal presence, and data link activity before takeoff.
