Abstract
We present the impact of frequency offsetting of strong (e.g. 35Â GHz) optical filters on the performance of 42.7Â Gb/s 50% RZ-DPSK systems. The performance is evaluated when offsetting the filter by substantial amounts and it is found that with an offset of almost half the bit rate there is a significant improvement in the calculated 'Q' (>Â 1Â dB). We deployed balanced, constructive single ended and destructive single ended detection, so that we could investigate the physical origins of the penalty reduction of asymmetric filtering of 42.7Â Gb/s 50% RZ-DPSK system.
