SANLAND's innovative controllable RFoF product line consists of palm-size analog RFoF modules that are used to convert RF signals to optical signals to carry over long distances. The Tx unit using an optical transmitter, converts RF to the optical signal and the Rx unit converts back to the RF signal. The two units are connected through the customer’s single-mode fiber.

SANLAND's RF over Fiber (RFoF) modules are suitable for telecommunications, satellite, radio telescopes, distribution antennas, broadcasting audio and video, and timing synchronization. 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 by RF over Fiber solutions.
