Abstract :
The multi-channel 2R regenerator with group velocity delay (GVD) compensation utilizing four-wave mixing (FWM) in a piece of highly nonlinear fiber (HNLF) is proposed for the first time. A 2R regeneration of 8×12.5Gb/s synchronized return-to-zero (RZ) signals is numerically simulated. The maximum sensitivity improvement of the receiver (bit-error-ratio BER=10-9) is about 2.38dB. The large dynamic dispersion compensation up to 500ps/nm in each channel can be obtained. Our analyses show that the performance of the multi-channel 2R regenerator is related to the channel spacing and the frequency interval between the pump and the probe.
