Cancellation of the signal fading for 60 GHz subcarrier multiplexed optical DSB signal transmission in nondispersion shifted fiber using midway optical phase conjugation

In millimeter-wave (mm-wave) optical double side-band (DSB) signal transmis sion systems, the received radio frequency (RI) power fades periodically be cause of the group velocity dispersion (GVD) and the self-phase modulation (SPM) of optical fibers. In this paper, cancellation of the signal fading b y using midway optical phase conjugation in mm-wave subcarrier multiplexed (SCM) optical DSB signal is analyzed. Fading-free 60 GHz mm-wave optical DS B signal transmission over 100 km-long nondispersion shifted single-mode fi ber at 1550 nm by using a semiconductor optical amplifier (SOA) optical pha se conjugator (OPC) in the midway of optical link is experimentally demonst rated for the first time, Finally, the degradation factor of the OPC system is also discussed.
