Can anyone help to understand this? because this is wired & confusing!
why optical hard limiter has the blueish pulse shape at some sweeps when the bit rate is 1Tbps, but it works fine when bit rate is below 250gbps, how to solve it?
anyway i uploaded the file of optisystem 7.
Thank you.

Hi Hell,
I see what you have said in your example.
I have tried the example titled (Optical Hard Limiter.osd) provided with OptiSystem, and it works well even with 1 Tbps.
I think the problem with you example is that, there are two cascaded OHL, and you sweep the upper output limit. -

Hi Abouseif,
yes you are absolutely right,
OHL is malfunctioning wile connecting as cascade. when i replace OHL at source with NRZ Pulse Generator it works fine.
So i think that optisystem team should notice this kind of issue & fixed them. 🙂
thanking you
