The performance of a pre‐amplified cross‐phase modulation (XPM) wavelength converter has been theoretically investigated. We showed that the pre‐amplifier enhances the input optical power dynamic range by 3 dB. The additional 4‐dB improvement of the power penalty in wavelength conversion obtained through BER simulation shows that integrating a pre‐amplifier enables the accommodation of a relatively small input optical power.
