RFoF - 2.5 GHz

RFoF - 2.5 GHz

RFOptic’s palm size analog RFoF modules are used to convert RF signals to optical signals that can be carried over long distances. The Tx unit using an optical transmitter that converts RF to Optical signals and the Rx unit converts them back to an RF signal. 

RFoF - 2.5 GHz

RF Optic’s RF over Fiber modules (RFoF) are suitable for telecommunications, satellite, radio telescopes, distribution antennas, broadcasting audio and video, timing synchronization and GPS applications. For example, point-to-point antennas can be connected from several meters to many kilometers away from the control room by fiber cables; Base stations can be connected through fiber to remote sector antennas; Satellite antennas can be connected through fiber cable to remote sites via by RF over Fiber solutions.

Both the Tx and Rx units include: LNAs and variable attenuators that enable the customer to adjust the Noise Figure, Input P1dB, IP3 with wide dynamic range values. The LNA can be operated through the RFoF Software allowing RF input power in the range of -100 dBm/1MHz for wideband applications, with a low Noise Figure of 6 dB. The RFoF link has excellent gain flatness with 0.5dB gain tracking between different links. For special applications requiring temperature stability operation, a unique algorithm supporting 0.5 dB over 100°C has been developed. The DC power of the RFoF modules has a flexibility of 5 to 12 Volts.

Furthermore, the RFoF link has contains a full diagnostic capability including Tx, Rx and complete link test (Optical and RF). These features provide significant savings in terms of test equipment and provide real time diagnostics of any deployed link.
