Abstract : In millimeter-wave(mm-wave) optical double side-band (DSB) signal transmission systems, the received radio frequency (RF) power fades periodically because of the group velocity dispersion (GVD) and the self-phase modulation (SPM) of optical fibers. In this paper, cancellation of the signal fading by using midway optical phase conjugation in mm-wave subcarrier multiplexed(SCM) optical DSB signal is analyzed. Fading-free 60GHz mm-wave optical DSB signal transmission over 100 km-long nondispersion shifted single-mode fiber at 1550nm by using a semiconductor optical amplifier (SOA) optical phase conjugator (OPC) in the midway of optical link is experimentally demonstrated for the first time. Finally, the degration factor of the OPC system is also discussed.
