2.5GHz RF Over Fibre For GPS

RFOptic presents its new innovative controllable RFoF product line. RFOptic's palm size analog RFoF modules are used to convert RF signals to optical signals to carry over long distances. The Tx unit using an optical transmitter, converts RF to Optical signal and the Rx unit converts back to RF signal. The two units are connected through customer’s single mode fibre. RFOptic's RF over Fibre modules (RFoF) are suitable for telecommunications, satellite, radio telescopes, distribution antennas, broadcasting audio and video, timing synchronisation and GPS applications. For example, point-topoint antennas can be connected from several meters to many kilometers away from the control room by fibre cables; Base stations can be connected through fibre to remote sector antennas; Satellite antennas can be connected through fibre cable to remote sites by RF over Fibre solutions.Features
