Abstract
This paper investigates the computational time and accuracy of several alternatives for the estimation of the GSNR of coherently detected signals in multi-band transmission (MBT) systems. The considered optical performance estimation methods are the closed-form ISRS-GN, the FWM, the enhanced FWM, and the numerical GGN (used as a reference). A comprehensive set of results suggests that the closed-form ISRS-GN model has the best trade-off between computation time and accuracy in the evaluated scenarios, enabling fast but still reasonably accurate optical performance estimation for MBT systems with transmission bandwidths up to 20 THz.
