10 Determine SSE power values inside the transmission bands:
a Ensure the TLS is set to TLS_l0 and is not changed.
b On OSA, set marker to OSA_l1.
c Check the OSA and note SSE power value in [pW] in the table
below as SSE_power.
d Increase OSA marker wavelength by 1 nm.
e Repeat steps c and d until the wavelength is equal to OSA_l2.
f Set OSA to OSA_l3.
g Repeat steps c and d until the wavelength is equal to OSA_l4.
h Add up all power values inside the transmissions bands to get
the value of power_trans.
NOTE Note all the power values in the table in [pW], where 1 pW = 10
