      Hello,

      When i try to set up a back to back 100G DP-QPSK system, Number of Y Symbol Errors = 8684, while X Symbol is 0. Not sure which cause the failure on Y polariation. I can’t see any abnormal on constellation figure.
      I try to change several parameters, to same as the example file “112Gbps Coherent DP-QPSK_B2B_subsystem with DSP.osd”, still can’t make it work correctly.
      Could someone help to check where i’m wrong? file is attached.

      Thanks!
