why i am not getting BER graph ?

[Ibn Aziz]

Hi Every one!

I am working on a project in which i need to find a BER of the scenario as shown in attachment given below.

I got results(curve) at the very last filter at receiver side but don’t know why i am not getting BER curve.

I am working hard to find the BER curve but don’t know why i am not getting this graph .

If any one know the reason plz share.

i wil be very thakful to u for ur this act of kindness.

(i am using optisystem 7)

Best Regards
Best wishes

I am getting Q value after changing Bit rate to 10 Gbps.

I think the BER Analyzer is having trouble centering the eye diagram because of the 25 GHz range and your actual bit rate being at <1 GHz. Setting the last filter to 0.8 GHz makes a much nicer eye diagram.
