      Dear Emrah,
      The noise figure of an EDFA can’t be negative. The minimum possible noise figure of an EDFA is 3.
      I guess the placement of the input and output terminals of the dual port analyzer is not correct.
      Please send me the project as a zip file to my email at @optiwave.com">ahmad.atieh@optiwave.com to fix the issue.
      Regards,
      Ahmad
