Hi Ravil,
it does really depend on number of channels/spacing/power of the EDFA. But from my experience, when you use erbium fiber with low doping concentration (which means that you need a longer piece of fiber to reach the same gain) you are exposed to the FWM problem inside the edfa itself.
Does this reply to your question?
