Abstract

We experimentally demonstrated 800-Gbit/s/carrier WDM coherent transmission over 2,400-km based on 100-GBd truncated PS-64QAM utilizing 75%-sparsity pruning DNN-based nonlinear equalization. Results show that our pruning DNN-NLE with 24%-lower complexity outperforms Volterra NLE by 20% reach improvement.
