Optical Sampling Modules
5.
Do the following substeps to check the clock recovery optical sensitivity
range:
a.
Find the module under test listed in the following table.
b.
Adjust the variable optical attenuator until the Average Optical Power
(AOP) measurement for C1 matches the value given in the AOP
Measurement
Max optical power
column for the module under test.
c.
Check that the clock signal remains stable.
d.
Adjust the variable optical attenuator until the Average Optical Power
(AOP) measurement for C1 matches the value given in the AOP
Measurement
Min optical power
column for the module under test.
e.
Check that the clock signal remains stable.
