Effectiveness of digital back-propagation and symbol-rate optimization in coherent WDM optical systems

We apply DBP to an experimental WDM system where multisubcarrier transmission provides a 12% reach gain vs. single-carrier. DBP provides further gain for both single- and multisubcarrier systems but significantly underperforms ideal theoretical predictions.
