For the first time, all-optical wavelength conversion of a 2.488-Gb/s signal with simultaneous suppression and replacement of a low-frequency wavelength-identifying pilot tone has been demonstrated using an integrated semiconductor optical amplifier/distributed feedback laser. In addition, the conversion process has been shown to allow eye noise removal, leading to negative bit-error-ratio penalties as high as -1.6 dB.
