Radio over Fiber (RoF)

Radio over Fiber allows to convert a RF signal to an optical one, benefiting from fiber transport advantages, such as:

• Low loss (0.5dB/km @ 1310nm, monomode fiber).
• Immunity from external electromagnetics noises (power lines, signal path...).
• Small and lightweight.
• Can be mounted on drum and deployed quickly on field.
• No oxidation.
• Low price of fiber.
• Wavelength multiplexing for sharing medium.

TX and RX, when speaking about radio over fiber equipments means that TX stand for optical emission and RX stand for optical reception. For example, a RF source or antenna is connected to the FTX-1 which emit optical signal on fiber. The FRX-1 receive an optical signal then convert it back to an electical signal.

At BSRF we design our own radio over fiber (RoF) converters. We designed them to achieve the best compromise between dynamic and noise.

Our converters use 1310nm and 1510nm wavelength as standard but we can do WDM or CWDM if needed as an option.
