Fiber nonlinearity compensation by digital backpropagation of an entire 1.2-Tb/s superchannel using a full-field spectrally-sliced receiver
22 September 2013
We receive the full optical field of a 176-GHz wide, 1.2-Tb/s PDM-16QAM superchannel after 960-km TWRS using a spectrally-sliced coherent receiver. Simultaneous compensation of SPM and XPM with digital backpropagation enables 1 dB of Q-factor improvement.
