      Dear all,

      In EDFA, when I increase Noise Figure, does it make the better performance or not?

      Regard,

      Hi lim,

      Increasing noise figure for all optical amplifiers (EDFA, Raman, or even the black box optical amplifer component in OptiSystem amplifiers libray) means increasing noise, since noise figure is defined as the ratio of SNR at the input to SNR at the output of the amplifier (or any other component).

      Regards

      Hi Lim, as mentioned by Alitsu, an increase in Noise Figure is an increase of the noise generated by the amplifier, so the performances are worse.

      Best Regards,

      Alessandro
