Hello everyone,

Could anyone help me to know if my design is correct or not because I struggle with it, I am working to do Colorless ONUs based on SOA in U-DWDM-PON, and I have got a very low Q-Factor and high BER. I would be more than grateful if to let me know what am I supposed to do.

I will highly appreciate a positive response regarding my issue.

Kindly find attached the file,

Sincerely,

Tariq Mohammed

      Dear Tariq,
      I’ve noticed that your connection to the R-SOA is not correct. Please follow the example (Reflective SOA.osd) in the example library for guidance. Also, note that the BW of the MUX/DEMUX AWG is two wide (10GHz) compared to the modulated signal (2.5Gbps) and this will cause more interference at the receiver and during propagation.

      Regards,
      Ahmad
