We experimentally demonstrated a novel radio-over-fiber scheme to simultaneously obtain independent wired and wireless signals by using only a single intensity modulator. The optical 40- or 60-GHz millimeter-wave (mm-wave) carriers are generated by means of subcarrier-multiplexing techniques to carry 2.5-Gb/s wireless signals while 10-Gb/s wired signals are imposed on the original optical carrier via regular intensity modulation. The signals with dual services are successfully transmitted over 20-km single-mode fiber (SMF-28) with less than 1.5-dB power penalty.
