Optical signal spectrum prediction using machine learning and in-line channel monitors in a multi-span ROADM system
We measure the performance of separately characterized machine learning-based EDFA
models for predicting the optical power spectrum evolution in a 5-span system with six ROADM nodes
deployed in the COSMOS testbed, which achieve a mean absolute error of 0.6–0.7 dB after 10 EDFAs
under varying channel loading configurations.
