Linear Neural Network Enabled Optical Performance Monitoring from Directly Detected PDM-QAM Signals

Asia Communications and Photonics conference and Exhibition, 2022
We experimentally demonstrate a linear neural network (LNN) enabled optical performance monitoring (OPM) for PDM-QAM signals, by using the amplitude histogram (AH) generated from the direct detection. When both 10Gbaud PDM-QAM16/64 signals are considered,
