Peak Count
Signal count
Gain Slope
Slope when a straight line approximation is
performed based on the gain obtained for each
optical signal.
Gain Vari
Ratio between the maximum gain and the
minimum gain
No
Number of signal (sequential number added from
short wavelength)
Wl (nm)
Wavelength of signal
Pin (dBm)
Optical signal level input
Pout (dBm)
Optical signal level output
ASE (dBm)
ASE level for signal
Res (nm)

NF (dB)
Noise figure
The noise figure and gain are calculated from the power of the optical
input to the optical amplifier (Pin), the power of the optical signal output
from the optical amplifier (Pout), and the ASE level.
Refer to 5.8.4 “Calculation Method” for details.
Pin, Pout, and ASE are measured from the optical input to the optical
amplifier and the spectrum of the optical output of the optical amplifier.
