Continual Pdl Drift Detection and Estimation in Optical Networks
We propose a novel method for continual PDL monitoring that first detects PDL drift by tracking SNR distributional shifts at the receiver, and then provides a prediction of the updated PDL value. This approach achieves a root mean square error (RMSE) of approximately 0.15 dB over time.
