UHF over optical fiber,
compact and plug-and-play.
The FTX-1 is a compact simplex Radio-over-Fiber emitter. It converts a UHF electrical signal (470–690 MHz filtered, or 0.1–3 GHz unfiltered) to a 1310 nm monomode optical signal. Integrated active-antenna DC feed on the BNC, XLR4 power, two input modes, 33 × 33 × 110 mm form factor. Compatible with every BSRF RoF receiver. Made in France.

Highlights
Two input modes
High-Sensitivity mode 470–690 MHz filtered/amplified +12 dB to pick up faint HF signals; Low-Sensitivity mode 0.1–3 GHz unfiltered with 0/−10/−30 dB attenuation to accept a transmitter up to 50 mW directly.

RoF linearity
32 dBm typical OIP3, noise figure < 2 dB: RF-to-optical conversion preserves the dynamic range and cleanliness of the original signal across the link.

Integrated antenna DC feed
The input BNC carries remote power toward an active antenna (Vin/200 mA): a single coaxial run from antenna to FTX-1, no second power line.

IP / rack integration
33 × 33 × 110 mm, aluminum, XLR4 power: the FTX-1 mounts in an outdoor enclosure, on a mast or near a rooftop antenna without drawing attention.

Use cases
Long-distance antenna offset
Route a rooftop antenna without coax loss
UHF antenna → short BNC → FTX-1 in High-Sens → monomode fiber back to studio → AFR-250S or AFR-200 on reception. No line amplifier, no 0.4 dB/m loss.
HF video / camera feed
Carry a wide-band camera signal over fiber
Low-Sensitivity mode 0.1–3 GHz with −30 dB attenuation: plug a camera transmitter's antenna output (up to 100 mW) directly and carry the signal over fiber back to the control room.
Remote measurement
Capture an RF spectrum hundreds of metres away
Measurement antenna → FTX-1 → fiber → FRX-1 → spectrum analyzer. Complete galvanic isolation, total immunity to EM disturbances along the run.
