This paper demonstrates a multichannel wavelength conversion of differential phase-shift-keyed (DPSK) signals using four-wave mixing-in a highly nonlinear fiber. The wavelengths of three 10-Gb/s nonreturn-to-zero (NRZ) DPSK channels are simultaneously converted without incurring the cross-gain modulation penalty usually associated with ON-OFF-keyed signals. A maximum conversion efficiency of 85% was achieved for both NRZ and return-to-zero DPSK signals.
