Performance Tests
V. Polarization Dependent Loss (PDL): Optional
approximated:
The associated Test record will look like this by adding the
appropriate values to those of the Linear Horizontal polarized
light.
10. Measure the Reference Power
a. Linear Horizontal polarized light.
Keep the setting from the polarizer and the
λ/4 and λ/2 Retarder
Plates from steps 6. to 8.
• Read the power that is displayed on the power meter and
note it as P
01
in the test record.
