Experimental Demonstration of Soft Failure Identification Based on Digital Residual Spectrum and Machine Learning

While machine learning (ML)-based soft failure management in optical network is flexible and efficient, several challenges stand in the way of its actual deployment. The performance of a trained model in unseen systems is a key issue. In this paper, a soft failure identification (SFI) algorithm based on digital residual spectrum and machine learning is verified by experiments. This algorithm facil...
