Measuring Power or Loss (FPM-600 and FOT-600)
Measuring Power or Loss
Measuring Power or Loss
Measuring absolute power or link loss is done the same way, except for the
referencing step.
To perform power or loss measurements:
1. If necessary, perform an offset nulling (see
Nulling Electrical Offsets
on
page
18).
2. Check and clean your fibers appropriately for optimum performance
(see
Cleaning and Connecting Optical Fibers
on page
16).
3. For loss measurements, reference your power meter to a light source
(see
Referencing Your Power Meter to a Source
on page
23), then
deactivate the light source.
4. Using the proper adapter and test jumpers, connect a fiber under test
to a light source (such as FLS-600) and to the detector port of your unit.
Note:
If you have referenced your power meter to a source, simply connect a fiber
under test to the test jumpers used for referencing.
5.
Activate the source at the desired wavelength.
