      Hi Patil,
      To create a subsystem, you just need to select its all component and by right-click just choose “Create Subsystem”
      To check the subsystem components just double click on it, then another subsystem window will open having the subsystem elements.

      Hope that helps,

      Hi Patil,
      I will try to check your file, but in the mean time try to trace the signal from one point to another to catch the position where the signal disappear.

      Hi Patil,
      I check you program,
      please check “Show Eye Diagram” on right of the BER Analyzer.
      I did and could see some data (not sure correct or not but there are numbers). Then try to modify you system according to your needs.

      thanks

      yeah, I already checked that. It is not giving Min-BER as expected.

      so you need to adapt your system parameter, I think It is a design issue.

      thanks

      Design parameters are very similar to that given on optiwave video. Also, I referred some papers they have same parameters.

      did you build the example or download it from somewhere?
      if so can you provide me the link to download it.

      I downloaded it from optiwave discussion. Modified according to my need. Changed design parameter
