      Dear Ayat,
      there are few examples that exist in OptiSystem that you may use for your project. They are based on scripting.

      thanks Mr. Ahmad for your reply.
      the example is very useful but need more clear for me.
      plz can you tell me how to change the noise ratio since the BER test set component export the data for 1 iteration?

      Best regards

      Dear Ayat
      You can change the OSNR by combining a white light source with your laser source.On changing the power of white light source,the OSNR may be changed and you can get OSNR value by using a WDM analyzer or Dual port WDM analyzer which will show you the OSNR value and corresponding BER too.
      regards
