Erbium doped fiber amplifier
I’m working on the erbium doped fiber amplifier. I designed a simple configuration of single-pass EDFA. I used a dual port WDM analyzer to calculate the gain and noise figure characteristics.
As I know, the noise figure is calculated by using this equation: NF = (SNR)in – (SNR)out.
However, I got different NF when I used the equation above (please see the attached photo).
Could you please inform me what the equation that used by dual port WDM analyzer to calculate the NF.
