Abstract: An automated methodology for optical line systems integrating probing transceivers to initialize a system-level digital twin is described. Physical model parameters are inferred from scratch by combining end-to-end spectrum measurements, pre-FEC BER and optical amplifier telemetry, enabling near-optimal configuration, model alignment, and precise QoT tuning.
