N2 - This paper has proposed a radio-over-fiber (RoF) link carrying two 10Gb/s 16-QAM mm-wave signal streams. Since the dual-tone 40GHz optical mm-wave are generated by frequency quadrupling via a LiNbO3 modulator and the two QAM signal streams are modulated on each tone by single sideband (SSB) modulation, the frequency requirements of the RF local oscillators and the optical modulators are reduced to 10GHz, which means a cost-effective RoF implement. Since the mm-wave signals in the photocurrent are generated by beating in a SSB pattern, the optical mm-wave signal has great tolerance to the fiber dispersion. Moreover, one optical mm-wave carrier carries two16-QAM 10Gb/s data streams, our link scheme has a higher bandwidth efficiency. The simulation results show that both the constellation diagrams and the eye diagrams of the two different QAM streams are well accepted even after 60 km fiber transmission.
