      You can try using our digital signal processing component to manage the rotation of the constellation diagram.

      In my opinion, this rotation may be introduced by the dispersion caused by optical fiber. So, if you use equalizer, it will compensate the rotation.

      In other hand, you can get off “nonlinear effect” in SMF. But, Damian Marek said, that equalizer and DSP for QAM system is great choice. I am agree with him)
