Abstract :
In this paper, we examine for the first time to our knowledge, the potential of all optical regeneration for multiple input wavelengths at bit-rates beyond 40 Gb/s. The system parameters have been investigated assuming two and four channel operation. Successful regeneration has been achieved for two input channels at 40 Gb/s and 160 Gb/s. Four channel operation at 40 Gb/s has been investigated as well, illustrating Q-factor improvement and amplitude fluctuation suppression at the marks.
