      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.

      thank you Abouseif
      here is the file
      OHL shows wired behave to it’s input near its threshold value at 1Tbps

      i don’t know why? but until i did not find any reason. this is annoying.

      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
