In this paper, the performance of a 60 GHz radio over fiber free space optics (RoF-FSO) communication system with 10Gbit/s 4-ary pulse amplitude modulation (4-PAM) polarization shift-keying (Polsk) downlink signal is proposed and designed. In the receiver, the 60GHz millimeter-wave with 4-PAM downstream signals is generated by the beating of two continuous light waves, and the high frequency signal is demodulated by self-mixing zero difference detection method. Meanwhile, the optical spectra, radio frequency (RF) spectrum, eye-diagram are measured, and the transmission performance of the used RoF-FSO system are analyzed.
