Abstract :
We investigate the performance of electronic chromatic dispersion compensation of 10-Gb/s Manchester coded optical signal using a feed forward equalizer (FFE) and decision feedback equalizer (DFE). Utilizing offline signal processing, the performances of FFE-DFE with different number of taps and input sampling rates under both cases of single-ended and balanced detection are compared. Experimental results show that the transmission distance of Manchester coded signal can be increased by a factor of three with four-sample-per-symbol FFE-DFE.
