We have studied the influence of degenerate four wave mixing (FWM) on the performance of the multiwavelength continuous-wave (CW) optical source based on supercontinuum (SC). By suppressing degenerate FWM, a 100-channel SC CW optical source with 25-GHz spacing for 10-Gb/s dense wavelength division multiplexing (DWDM) systems is experimentally demonstrated. Confirmation is provided with the generation of CW channel with crosstalk of other channels less than -28 dB and the presentation of 10-Gb/s eye diagram and bit error rate (BER) performance.
