Abstract
Longitudinal Power Monitoring (LPM) enables DSP-based receiver-side reconstruction of the optical power evolution. This paper reviews recent LPM techniques and implementations, and demonstrates its use for nonlinear interference estimation and span-wise power optimization, enabling accurate, model-light, and scalable performance monitoring in real-world optical networks.
