Experimental Demonstration of 200 Gb/s/λ Coherent PON with a Low-Complexity Receiver and a Multi-purpose Neural Network

Abstract

We experimentally evaluate a single-BPD-based polarization-insensitive coherent receiver for 200 Gb/s/λ PON. A neural network is used as a joint equalizer and Alamouti decoder. A 29 dB power budget is achieved with 20 km transmission.
