      Could you please post a bidirectional WDM OFDM PON example here or at least bidirectional OFDM example? Thank you!

      Try looking at this:

        Hi Damian,

        I check the design that you attached in the link above, and I am thinking if I can use just one OFDM modulator with 4 ports at transmission side in the OLT. in the receiver side, we split the optical signal to four, then we down converter to RF each one spirit.

          Hi Mohamed,

          I once tried to implement such a system but did not manage to. Can you please share your implementation if it is possible for you? Thank you.

          Regards

          Hi Alistu,

          sorry for late reply.
          actually I am still working on it, in the attached file you can see the configuration of the OFDM PON that I am working with it (version 0). once I complete and improve the last version, I will submit it in the forum.

        Hi Damian,
        Thanks for your help. The example you attached here (https://optiwave.com/forums/topic/ofdm-uwb/) will not give good results if you enable optical fiber simulation?

      Thanks Damian for your reply. I have seen this example before. I am trying to set up a bidirectional system. I am using OS13. Any help will be highly appreciated!

      are you facing a problem in bidirectionality only??

      Thanks. I have simulated many bidirectional systems but I think there is a problem with the OFDM ones.

      I think they should post an example of A bidirectional OFDM

      Hi Fady,
      Here i am attaching osd file bidirectional WDM OFDM PON.
      It cotains of 2 transreceivers.

      Thanks Ranjeet, I could not open the file. I am using OS-13. Regards

      Hi Fady,
      I am understanding your problem why there having problem in opening file iam using Optisystem 14 but getting good q-factor and BER.
      Although its simulation time is 7 minutes nearly. I again uploading the osd file may be this help you.

      Thanks Ranjeet but still can not open the file

      Hi Ranjeet,
      I have opened the file using OS14. Why you are using OFDM OS12 components in your work. You should use the new OFDM components to get better BER results.

      Hi Fady,
      Thanks for your suggestions, i am trying to use OFDM modulator and demodulator.
