Experimental measurements of uncompensated reach increase from MLSE-EDC with regard to measurement BER and modulation format.
Comprehensive experimental measurement data are presented comparing the performance of an optical receiver with MLSE-EDC technology against a standard receiver for signals with uncompensated chromatic dispersion. Signals with the NRZ and duobinary modulation formats are investigated. We find that the MLSE-EDC technology provides greater uncompensated reach advantage for both formats as the allowable measured BER is increased, demonstrating the EDC technology has greatest effect and application in conjunction with strong forward error correction. We also measure signal quality vs. dispersion with constant OSNR and draw similar conclusions along with further insights into the application space of the EDC technology for both modulation formats.
