A full-duplex radio-over-fiber (RoF) link with a novel scheme to generate 60GHz mm-waves from a 5GHz RF signal source is investigated. In the RoF downlink, the required frequency of the RF oscillator is reduced greatly. Since the optical carrier is not modulated by downstream data, part of it is reused to carry upstream data and the upstream data is transmitted to the central station using optical...
