Abstract

We review the advancements in Rx DSP-based transmission-link monitoring methods, which reveal fiber-longitudinal distributions of various physical parameters (e.g., signal power profile, gain spectra, and filter responses) along a multi-span link without analog testing instruments. We also discuss the comparison of power profile estimation methods.
