hi zulkarnain,,,
Radio-over-fiber (RoF) is a technology used to distribute RF signals over analog optical links. In such RoF systems, broadband microwave data signals are modulated onto an optical carrier at a central station (CS), and then transported to remote sites or base station (BS) using optical fiber. The base-stations then transmit the RF signals over small areas using microwave antennas.
