      Dear Sir/Madam,

      I want to perform frequency up-conversion optically. But In all the cases of fiber transmission, I have obtained BER=1 & Q-factor=0, after the low-pass filter placed at the receiving side. The similar problem persists for the other methods as well. So, please provide a solution for this problem.
      The set-up and BER analyzer outputs are attached for reference.

      Dear Ankita,
      I went through your design and found that the mixing at the receiver end is not correct. Why did you choose 32GHz sine wave?
      Do you have a reference paper that you use for this design?
      Please email me at ahmad.atieh@optiwave.com for further discussion.
      Regards,
      Ahmad
