We experimentally investigate, in a 2x56-GBd 400G WDM transmission system, different approaches for nonlinear compensation in spectrally-sliced optical receivers with MIMO-based signal reconstruction. Slice-by-slice nonlinear compensation shows comparable performance to inter-slice nonlinear compensation in a WDM system. In addition, an 8-stages compensation yields a 0.4-dB Q2 gain equivalent to 250-km distance increase, resulting in 2000-km transparent reach.
