Title

Influence of IF-filtering on bit error rate floor in coherent optical DPSK-systems

Abstract
The authors investigate the influence of IF-filtering on the bit error rate floor in optical DPSK-systems; this influence is usually neglected. They show that the IF-filtering leads to a reduction of the error rate floor, so that the linewidth requirements are reduced by a factor of 0.68.
