Abstract
A full-duplex radio over fiber system with optimum optical carrier to sideband ratio (OCSR) of 0 dB and wavelength reuse for uplink are proposed. At the central office, single-sideband modulation with OCSR larger than 0 dB is realized based on optical injection. At the base station, a notch filter with the notch depth corresponding to the OCSR of the transmitted signal is used to achieve the optimum OCSR of 0 dB. The reflected weakly modulated carrier is reused as the carrier for upload signals. A simulation is carried out to verify the proposed system. Results show that the download 60-GHz-RF signal is almost not affected by the fiber chromatic dispersion, and the power penalty after transmission over a 50-km single-mode fiber is negligible in uplink and is only 1.27 dB in downlink.
