Abstract
A wavelength division multiplexed (WDM) radio over fiber access network architecture, capable of simultaneously transmitting both 63 GHz wireless and wired data, is proposed in this paper. An optical carrier suppression effect and multiplexing of a 50 GHz spaced arrayed waveguide grating are employed to generate a 63 GHz millimeter-wave signal based on WDM. These techniques allow the proposed scheme to simultaneously transmit both wireless and wired data. For full colorless operation, a reflective semiconductor optical amplifier is used at the central office and base station. Error-free simultaneous transmissions [wired data: bit error rate (BER) of , wireless data: BER of ] of wired data and wireless data are achieved. Various impacts of the downlink transmission on the performance of uplink data are investigated with the proposed scheme.
