      Hello everyone , in my WDM design i am getting OSNR values as high as 95 dB or more at output . even the ouput of optical spectrum analzyer shows Noise in different band from signal which is possibly whz OSNR is high. but is it feasible ? if no then whz such high OSNR values exist at output even before amplification OSNR is near 66 dB at input.
      pls if anzbdz could suggest me something

      Hi Gaganpreet,

      can you please upload your design implementation so that I would be able to check it? Without seeing the design, it occurs to my mind that your problem might have something to do with your optical amplifier settings (perhaps the noise figure of the optical amplifier is being set to zero).

      Regards
