Dear @MirkoZETA, The current version of GNPy does not support the modeling of C+L amps yet, we are currently reviewing the new patches integrating this features and we expect to merge them in the next couple of months. In the mean time, as a workaround, you can try to set a constant gain in the EDFA and shape the actual gain profile on multiple bands using the EDFA parameter Also, if available, a precise set of fiber parameters can be provided to GNPy as profiles along frequency. This will increase the accuracy of the simulation, especially in wideband transmission scenarios. I hope this may help. |

Hello Team and Community,
I'm relatively new to GNPY, and I'm interested in using it to calculate the GSNR of a given lightpath as a performance metric in a Multi-Band system, specifically for C+L+S and C+L+E bands. I understand that setting the spectrum is fairly straightforward, but I’m curious if GNPY currently supports systems beyond C+L.
As mentioned in issue #508 by @EstherLerouzic "the fiber modelling properly supports multiband case, with proper SRS interband power transfer, the current release does not support the modelling of C+L amps yet, so that the same Edfa is used for both bands". Is this still the case?
My goal is to calculate this metric for a given topology and determine the feasibility of certain lightpaths. Any guidance or information on this topic would be greatly appreciated.
Thank you for your great work!
