• Value of f [Pin Loss]
Specify the difference between the level of the signal light input to the optical
spectrum analyzer and the level of the signal light input to the optical amplifier.
The unit is dB. Input a value down to the second decimal place.
Data range: –10.00 dB ≤ f ≤ + 10.00 dB
• Value of g [Pout Loss]
Specify the difference between the level of the optical amplifier output signal
input to the optical spectrum analyzer and the actual level of the optical amplifier
output signal.
The unit is dB. Input a value down to the second decimal place.
Data range: –10.00 dB ≤ g ≤ + 10.00 dB
• Value of h [NF Cal]
Specify a value for calibrating the result of NF calculation.
Input a value down to the third decimal place.
Data range: 0.100 ≤ h ≤ 10.000
• Value of i [O.BPFL-Cal]
Specify the difference in level between the pass and block ranges of the optical
band pass filter inserted between the optical amplifier and the optical spectrum
analyzer.inserted.
The unit is dB. Input a value down to the second decimal place.
Data range: 0.00 dB ≤ i ≤ 30.00 dB
• Value of j [O.BPF BW]
Specify an effective optical filter width (total ASE bandwidth) used for NF (total)
calculation.
The unit is always nm. Input a value down to the second decimal place.
Data range: 0.01 nm ≤ j ≤ 999.99 nm
• Value of k [Pol Loss]
Specify a level loss at the polarization control nulling stage used for polarization
nullification.
The unit is dB. Input a value down to the second decimal place.
Data range: –10.00 dB ≤ k ≤ 10.00 dB
