BER versus OSNR

[Fady]

Could you please show how to plot BER versus OSNR in Optisystem? Thanks

[Alessandro Festa]

You should go under Report/Grid and then select the OSNR from the visualizer you want and the BER from the BER analyzer

[Heitor Galvao]

You’re going to do the following, you will right-click on top of the block of BER, and there you will click in component view and you will see the value of BER, now for example depending on the network that are using you can use the WDM analyzer, which provides the value of the BER, or simplemesmente play in this equation
Log10 (BER) = 10.7-1.45 (OSNR), and use other software to make the plotting of graphs such as excel, matlab, origin. Success in your journey is what I desire

If you are also looking at statistical distribution you can also relate them by Q-factor…
