ScholarBank@NUS Repository. https://doi.org/10.1109/PGC.2012.6457974 | Abstract: | The one-step nonlinearity compensation method, i.e., nonlinear phase rotation (NPR), is shown to be affected by the amount of pre-compensated dispersion for coherent optical OFDM system with a dispersion unmanaged link. It is observed that NPR plus optimal percentage, around 50%, of dispersion pre-compensation is performing better than 1-step digital back-propagation (BP), with the same computational complexity. The optimized scheme results in a 2-dBm improvement in optimal launch power as well as 1.75-dB improvement in optimal signal quality compared to 1-step BP after 800-km transmission at the bit rate of 20 Gb/s. © 2012 IEEE. | Source Title: | 2012 Photonics Global Conference, PGC 2012 | URI: | http://scholarbank.nus.edu.sg/handle/10635/70955 | ISBN: | 9781467325165 | DOI: | 10.1109/PGC.2012.6457974 |
