Abstract

The effect of bandwidth narrowing due to cascaded ROADMs is investigated for DP 64-QAM systems impacted by transceiver noise. Data-aided DSP is used to cope with the reduction in total SNR and to mitigate the filtering-induced signal distortion. For a given channel SNR, the adverse effects of bandwidth narrowing are more pronounced.
