Abstract
Low-complexity nonlinearity compensation (NLC) is proposed for the upgrade of legacy NZ-DSF transmission systems. Simplified SPM compensation of 100G DP-QPSK channels co-propagating with 10G-OOK channels is performed on a straight-line NZ-DSF test-bed. NLC improvement helps to counteract the nonlinear-crosstalk penalties induced by OOK channels.
