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…
