RF Over Fiber (RFoF)

Introduction


RF over Fiber (RFoF) solutions convert analog RF signals into optical signals which are then transmitted over optical fibers and converted back to RF signals at various bands.  RFoF Solutions are designed to replace coax cables that degrade RF signals over long distances, typically longer than 150 ft.

RFOptic’s easy-to-use RFoF solutions are mainly used to connect remote antennas to central in-door locations over optical fiber in Communications, Satcom, Cellular, Defense, DAS, A/V and GPS applications. Since fiber is lighter than coax RFoF solutions are also used in weight sensitive application such as space, marine, airborne and balloon-based communication applications.

RFOptic’s Low Frequency solutions support up to 6 GHz while the High Frequency solutions support up to 20 GHz.  See below for details:

High Frequency RF over Fiber (RFoF) modules



The RF parameters such as S21, NF, and P1dB that are detailed on the spec sheets can be customized to requirements.

Customization through programming

A user-friendly RFoF software enables adjustment of the RF and Optical parameters, such as link gain, Noise Figure, P1dB, Optical power, LED indication and module information, either locally or remotely. Furthermore, the RFoF link has full diagnostic capability including Tx, Rx and complete link test (Optical and RF). These features save the cost of test equipment and provide the real-time diagnostic of any deployed link.
