Abstract

We realized 420-Gbit/s/channel WDM coherent transmission over 4,000-km ULAF utilizing a novel well-expandable Ring-Wise Neural Network equalizer (RW-NNE) targeted to PS-64QAM signals. Results show that our RW-NNE with 25.3%-lower complexity outperforms normal NNE by 25% reach improvement.
