c Set the TLS module:
•Set [λ], the wavelength, to λ
FBG
- 1 nm.
For example, 1520.5 nm - 1 nm = 1519 nm.
• Set [P], the output power to:
d Switch on the TLS output.
e Check and note the peak power level displayed by the OSA, and the
wavelength at peak power.
Press Peak Search in the Marker field.
f For all wavelengths within a ±1 nm window around each 0.1 nm
step, check and note the power level displayed by the OSA. Fill out
this table:
