Hi Erwin,
there is a webinar regarding “Nonlinear phenomena in optical fiber” using OptiSystem that describe 7 nonlinear phenomena: SPM, XPM, SS, SBS, SRS, FWM, and RS.
just go to this link (https://optiwave.com/resources/webinars/webinar-describing-nonlinear-phenomena-optical-fibers-using-optisystem/)
then register and you will receive the webinar explaining the examples.
hope that helps,
