      Hello Khadija Omran,
      Actually, we calculate Minimum BER in optisystem using BER Analyzer which is found in electrical part of visualizer component library.
      It is easy to find to Min. BER and Q-factor.
      Here i upload an osd file
      When you will double click on BER analyser, you will get value of Min. BER, Q-factor. You can get structure of eye diagram by just get tick on Show eye diagram tab in BER analyser window.

      Hello khadija,
      As rightly suggested by everyone how to visualize the results like in bit error rate ( BER ) and quality factor. Now the problem being that you are not able to get anything on the visualizer for BER and quality factor , well i suggest you to kindly upload the .osd file of your system design so that someone could help you.

        Hello khadija,
        Thanks for sharing the link but unfortunately it is some drop box and it needs to go for registration which is not convenient. It would have been more convenient if you would have been able to upload the .osd file here only. But i see your file is 24 MB file and you can’t exceed the file size. I suggest you to copy your all blocks and design a new file which could be smaller in size.
        Regards

      Hello khadija omran

      As far as i know .osd file can never be that big. And sorry i am having problems opening whatever you have uploaded.

      Regards
