10 Determine the limits of the transmission and attenuation ranges:
a Lower Transmission Band: λ
1
... λ
2
•OSA_λ
1
= OSA_λ
0
- 15 nm
•OSA_
λ
2
= OSA_λ
0
- 0.5 x Attenuation Band
= OSA_λ
0
- 1 nm
b Upper Transmission Band: λ
3
... λ
4
•OSA_λ
3
= OSA_λ
0
+ 0.5 x Attenuation Band
= OSA_λ
0
+ 1 nm
•OSA_
λ
4
= OSA_λ
0
+ 0.5 x Upper Transmission Band
= OSA_
λ
0
+ 15 nm

11 Determine the SSE power values inside the transmission bands:
a Ensure the TLS is set to TLS_λ
0
and is not changed.
b Set the OSA marker to OSA_λ
1
c Check the OSA and note the SSE power value in [pW] in the table as
SSE_power
d Increase the OSA marker wavelength by 1 nm
e Repeat step c and step d until the wavelength is equal to OSA_λ
2
f Set the OSA to OSA_λ
3
g g Repeat step c and step d until the wavelength is equal to OSA_λ
4
.
h Add up all power values inside the transmissions bands to get the
value of power_trans.
Record the "partial noise power level" values in a table in [pW], where
1 pW = 10
-12
W.
