Global Foxcom’s VHF/UHF Military Radio Link Extension System is built for tactical environments where antennas need to be placed far from radio equipment while maintaining RF performance. By converting the radio path to fiber, the system removes the distance limits of long coaxial cable runs and enables remote antenna placement up to 30 km away. The system includes a 1U Radio Unit (RSU), which interfaces with one, two, or more radios, and a 4U Antenna Unit (ASU), which connects to the antenna side and delivers up to 50 W of transmit power to each connected antenna.
This military RF over fiber radio system protects the radio side against transmit power overload and safeguards the antenna side against environmental degradation while maintaining full output power. With zero transmit loss circuitry, fast processing, advanced amplification, and high-performance filtering, it supports high-speed hopping modes, TX/RX switching below 1 ms, and narrow band filtering of the transmitted frequency.

What primary application is the Radio Link Extension System designed for?
The system is engineered for tactical military and defense communications where command shelters or personnel must be physically isolated from high-profile antenna masts (up to 30 km away) to mitigate targeted strikes, electronic warfare detection, and lightning hazards.
What are the main system units?
The system includes the RSU Radio Unit and the ASU Antenna Unit. The RSU is a 19-inch 1U unit, while the ASU is a 19-inch 4U unit.
How does the system handle rapid frequency shifts used in electronic counter-countermeasures (ECCM)?
Featuring built-in high-speed processing and zero transmit loss circuitry, the system fully supports standard, nonstandard, and military high-rate hopping modes without degrading signal synchronization.
What types of fiber infrastructure and optical connectors are required?
The system supports dual or single SMF-28 (or better) single-mode fiber utilizing DWDM / CWDM optical wavelength ranges. Standard connector options include LC-APC and SC-APC.
