Abstract

We demonstrate DSP-efficient mitigation of intrachannel and interchannel nonlinear impairments in dispersion-managed DWDM transmission by using channelized-FBG-DCMs and dispersion-folded digital-back-propagation, showing similar nonlinearity tolerance as dispersion-unmanaged transmission for 256-Gb/s PDM-16QAM signals over 12×100-km SSMF spans.
