Simultaneous all-optical frequency down-conversion technique based on cross-phase modulation in a high nonlinearity dispersion-shifted fiber is proposed and verified by simulation, and its application to a wavelength-division-multiplexing (WDM) radio over fiber (ROF) is proposed. Error-free simultaneous all-optical frequency down-conversion of the 16 WDM ROF upstream channels is achieved. The simulated results show the performance of WDM signals is in good accordance with a single signal without any interference, and the power difference of two beat frequencies of the down-conversion signal is independent of the optical local oscillator power. The wavelength span of larger than 20 nm for down-conversion signal can be obtained.
