GNPy Experimental Validation in a C+L Multiband Optical Multiplex Section

The GNPy quality-of-transmission estimator has undergone improvements and rigorous experimental validation in a $\mathrm{C}+\mathrm{L}$ multiband transmission scenario. This includes the incorporation of a disaggregated generalized Gaussian noise model, along with advanced modeling of amplifiers and transceivers. The recently proposed implementation demonstrates notable enhancements, offering highly accurate GSNR predictions on commercial $\mathrm{C}+\mathrm{L}$-band equipment while significantly reducing computation time.
