GNPy is a tool or software used for Quality-of-Transmission (QoT) estimation in optical networks. It is based on the Generalized Gaussian Noise (GGN) model, designed to predict the signal quality in fiber-optic communication systems. Specifically, GNPy is being enhanced and experimentally validated for C+L multiband transmission (which covers a broad range of frequencies in optical communication).

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

/in /by

The GNPy quality-of-transmission estimator has undergone improvements and rigorous experimental validation in a C+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 C+L-band equipment while significantly reducing computation time.
