Multi-channel Nonlinearity Compensation of 128-Gb/s PDM-QPSK Signals in Dispersion-Managed Transmission Using Dispersion-Folded Digital Backward Propagation
10 March 2014
We demonstrate nonlinearity compensation of 37.5-GHz-spaced 128-Gb/s PDM-QPSK signals using dispersion-folded digital-back-propagation and a spectrally-spliced receiver that simultaneously receives three signals, showing mitigation of intra-channel and inter-channel nonlinear effects in a 2560-km dispersion-managed TWRS-fiber link.
