Turnkey RF over Fiber
Systems
When coaxial cable runs out of gas — distance, loss, and interference limits — fiber takes over. Our RF over fiber kits extend antenna coverage reliably from 100 meters to multiple kilometers.
When Do You Need RF over Fiber?
Standard RG8/LMR coaxial cable loses signal fast. Beyond ~150 ft at UHF frequencies you're fighting insertion loss that active antenna combiners can't fully recover. At 500ft+ coax is essentially not viable without exotic, expensive cable. RF over fiber introduces near-zero transmission loss over any practical distance — ideal for large venues, stadiums, arenas, campuses, and multi-stage events.
Cable Loss Reference
Insertion loss at 700 MHz — the heart of wireless mic / IEM frequency ranges.
| Cable Type | 100 ft | 300 ft | 500 ft | 1000 ft |
|---|---|---|---|---|
| RG58 | ~5 dB | ~15 dB | ~25 dB X | X |
| RG8X | ~3 dB | ~9 dB | ~15 dB | X |
| LMR-400 | ~1.5 dB | ~4.5 dB | ~7.5 dB | ~15 dB X |
| RF over Fiber | <0.5 dB | <0.5 dB | <0.5 dB | <1 dB OK |
* RF over fiber loss is dominated by conversion electronics, not cable length. A 10km run has the same loss as 100ft.
Ideal Use Cases
- Stadiums and arenas — antenna positions hundreds of feet from the rack room
- Multi-building campuses where running coax isn't viable
- Theatrical fly systems — antenna on a fly piece, rack stays on deck
- Broadcast trucks where fiber infrastructure already exists
- Any run over 150 ft where LMR-400 would be impractical
- GNSS antenna distribution for microwave transport timing sync
How It Works
An RF-over-fiber link converts the RF signal (typically 400–900 MHz for wireless mics/IEMs) from coax to analog light on a single-mode or multi-mode fiber strand. A remote unit at the antenna position converts back to RF. Power is supplied via PoE or DC to the remote unit.
