Modelling and Evaluating Optical Transmission with the OCATA Optical Time Domain Digital Twin
Year: 2025
Type: conference-paper
Abstract: We review the basis of the OCATA digital twin, including the information that can be extracted from IQ optical constellations, how optical time-domain propagation can be modelled using Deep Neural Networks, and tuned from telemetry data. We cover from single channel to multiple sub-carrier signals and multi-band optical transmission. Applications of OCATA are afterward reviewed, including accurate quality of transmission (QoT) estimation and nonlinear noise mitigation.
