Through extensive computer simulations, a wavelength converter based on XPM (cross phase modulation) in dispersion shifted fiber is studied. The dependence of the performance of the wavelength converter on the parameters, such as input signal peak power, power of the continuous wave, the wavelength difference between the signal and the probe, fiber dispersion, fiber length and the bit rate of input signal is studied for the first time. The results show that the input signal peak power and fiber dispersion are critical parameters for this kind of converter. And the converter can convert signal at as high bit rate as 200Gb/s.
