Quality of Transmission (QoT) Estimation refers to the process of assessing and predicting the performance and reliability of data transmission over a communication network. It involves analyzing various parameters and factors that affect the quality of the transmitted signals and evaluating how well the network can deliver data with minimal errors, delays, and distortions.
We implement a cascaded learning framework using component-level EDFA models for optical power spectrum prediction in multi-span networks, achieving a mean absolute error of 0.17 dB across 6 spans and 12 EDFAs with only one-shot measurement.
