Penalty-free transmission of 127-Gb/s coherent PM-QPSK over 1500-km of NDSF with 10 cascaded 50-GHz ROADMs

We experimentally demonstrate penalty-free transmission of 127-Gb/s coherent PM-QPSK through a cascade of ten commercial 50-GHz WSS over 1500-km NDSF. Simulation results show that cascades of 40 such 50-GHz liquid-crystal based ROADMs is feasible.
