Sum of all SSE power levels:
• in lower transmission band ________ pW (1)
• in upper transmission band ________ pW (2)
Sum of all SSE power levels in transmission bands, add results in (1)
and (2)
power_trans = ___________ pW
11 Determine SSE power inside the attenuation band by interpolation:
a Check the power measured at OSA_l2 and OSA_l3.
b Mark that power value which is the largest of both and note it as
power_ OSA_l2,3_max
c Calculate the power inside the attenuation band by using
power_att = 1/2 ¥ power_ OSA_l2,3_max
= ___________ 10
-12
W = ___________ pW
NOTE Note all the power values in [pW], where 1 pW = 10
