      Dear,

      I design and simulate with the bidirectional fiber. But at the upstream, it doesn’t have the signal. Could anyone tell me detail about it. I can’t find any solution for long time.

      Hi San,

      While I wans’t able to troubleshoot your system (and I think the problem might have something to do with the way of using optical delay components), I noticed your demux channel wavelengths were not set according to your laser wavelengths in upstream. You have to correct this anyway to have results.

      Regards
