Impact of narrow optical filtering on 200-Gbit/s DP-16-QAM long-haul optical transmission

The effect of optical band-pass filtering on 200-Gbit/s DP-16-QAM systems is investigated for different pulse shapes, SSMF and LEAF. The results show the detrimental effect of optical filtering in the nonlinear tolerance for RZ50 and NRZ.
