Digital Twin for Estimating QoT Statistics in Presence of PDL and Transceiver Imperfections
Ambashri Purkayastha, Camille Delezoide, Vinod Bajaj +3
We propose a physics-based digital twin to predict the statistical QoT distribution of a realistic optical lightpath. We demonstrate up to 0.73 dB accuracy improvement in worst-cas…

Power-Aware Digital Twin of Coherent Optical Receiver
Ambashri Purkayastha, Camille Delezoide, Fabien Boitier +4
We propose a digital twin of coherent receivers based on an extended physical model for predicting quality of transmission under receiver power variations. We experimentally valida…

Accuracy Enhancement of an Optical Network Digital Twin Based on Open-Source Field Data
Ambashri Purkayastha, Cédric Ware, Mounia Lourdiane +2
We propose a two-stage hybrid QoT model for twinning a real transport network and evaluate it on recently published field data. Accounting for partial calibration of key parameters…
