RF‑over‑fiber makes it possible to transport analogue RF signals over long distances without loss, distortion, or external interference.This provides significantly better performance and flexibility compared to traditional coaxial solutions.
Typical applications:
- Satellite and ground stations
- Defence, emergency response, and secure installations
- Large campuses and industrial sites
- Radio and telecommunications infrastructure
- Test and measurement systems
Benefits:
- Frequency ranges from kHz to several tens of GHz
- Supports both simplex and duplex
- Fiber‑based switches offer high security, low loss, and no signal dithering
- Supports multiplexing (WDM) for many signals on a single fiber
- Substantially lower RF noise and crosstalk
Bredengen delivers complete RFoF solutions including transceivers, optical switches, fiber cables, and cabling.
Fiber‑based distribution of GPS/GNSS signals ensures reliable and precise time synchronization in systems that depend on absolute accuracy.
Why choose GPS‑over‑fiber?
- Stable distribution of L1/L2/L5 over long distances
- Transmission without electrical loss or noise
- Supports multiple simultaneous zones and redundant antenna points
- Can be integrated into existing fiber infrastructure
- High level of protection against spoofing, jamming, and manipulation
Applications:
- Data centers
- Telecom and mobile networks
- Power supply and the energy sector
- Defence and security installations
- Industrial control systems
Power‑over‑fiber is a technology that transmits energy through optical fiber – completely without copper.This enables the operation of electronics in locations where conventional power delivery is not possible, safe, or desirable.
How it works:
- A light source converts electricity into light
- The light is transmitted through an optical fiber
- A photovoltaic receiver converts the light back into electrical energy
- The generated power drives sensors or other electronics
Benefits:
- Complete electrical isolation
- Zero risk of sparks, ground faults, or EMI
- Lightweight – no heavy copper cables
- Safe operation in high‑voltage environments or strong magnetic fields
- Suitable for locations where cabling normally requires extensive approval processes
Applications:
- High‑voltage towers and transformer stations
- Underwater systems
- Medical equipment and MRI zones
- Military and aerospace
- Remote‑powered sensors and monitoring systems
Why fiber‑based signal and power distribution?
Fiber optics offer several decisive advantages compared to coaxial and electrical cabling:
- Extreme range – signals can be transmitted over many miles without amplifiers
- High security – fiber is very difficult to intercept and easy to monitor
- Immune to electromagnetic interference – no impact from EMI/RFI/EMP
- Low weight and easy installation – thin cables with minimal space requirements
- Future‑proof infrastructure – supports all formats, frequencies and bitrates
- Lower total cost – less equipment, simpler operation, and reduced maintenance
These advantages make fiber a natural solution for environments with high demands for precision, robustness, and operational stability.
