Analytical Models for QoT Estimations in Super-C and Super-C + L Bands Optical Transmission Systems

Abstract

We propose a novel physical model-based QoT estimation with achieved OSNR estimation error ≤ 1.5 dB in primary paths and OSNR prediction error ≤ 1.76 dB in unestablished lightpaths for both super-C bands and super-C+L bands for the first time.
