    Sir,

    The project file failed to open this time too. I am using a licensed version of Optisystem v.14. I also tried running it on Optisystem V.15 evaluation version but it failed to open on it too.

    Sir, it would be a great help if u could send me the screenshots of the modified project file.

    Sir,

    Kindly send me the project file and the screen shot of the revised project again as the previous one failed to open.

    Sir,

    I tried open the project file you designed but it won’t open (Failed to load document from the storage). Can you please upload the file again (also it would be nice if you can upload the snapshot of the modified design in case the file fails to reopen again)

    Thanks

    Sir,

    I tried simulating layout 2 again and yes Q Factor came out to be 0.626. But I believe that the Q Factor of the received signal should be better since we are using a back to back simulation. In case of data 1 the Q factor came out to be 221.613 whereas for data 2 it is only 0.626.

    Hello sir,

    Thank you for your worthy advice. As per your suggestion, I separated simulation projects for data 1 (NRZ), data 2 (DQPSK) and data 3 (PolSK) each transmitting at 40 Gbps datarate. After making some changes the individual projects are working as expected. The individual simulation projects are located in separate layouts in attached file.

    Now when I tried to combine data 1 and data 2 (Layout 2 in the attached .osd file), the data 1 (NRZ) is received correctly but BER analyzer at receiver side of data 2 (DQPSK) shows Quality factor=0 dB. I have tried to locate the source of error, but couldn’t find one.

    Sir it would be great help if you could look into it and suggest me the solution.

    Sir, I am trying to attach my project file along the mail, but due to some reason, the file is not being transferred along the mail. Can you please tell me your mail id so that I can forward you the project file.

    Sir, I have tried to duplicate the project file as described by the authors, but the results are not as expected. I tried to run back-to-back transmission simulation. Even then the output shows no signal (Q Factor=0). I think there is some issue with the simulation/component parameters I have considered.

    Sir, I am attaching the project file along this mail. Kindly, look into it and suggest me further improvements. I shall be very thankful..
