Hello everyone.
I´m trying to run an Optisystem simulation of a 4-QAM coherent system (version 7.0), but it doesn’t work. What I’m trying to obtain is the Eye Diagram while I change the lenght of the fiber through iterations, but it doesn’t make any effect in the BER analyzer (It shows always the same response).
I´ve taken a sample from the folder that comes with the installation to run the simulation, and when I watch the output on the Electrical Constellation Visualizer, it does show what I am trying to watch on the BER Analizer (changes in the signal as I change the fiber length).
I don’t understand what’s going on. Can someone help me, please?
Thank you all!
