Measuring Power or Loss

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.
2. Verify and clean your fibers appropriately for optimum performance.
3. For loss measurements, reference your power meter to a light source,
then deactivate the light source.
For more information on referencing, see Referencing Your Power
Meter to a Source on page 21.
4. Using the proper adapter and test jumpers, connect the fiber to test to
the light source and to the detector port of your unit.
Note: You can set the reference with one, two, or three reference jumpers.
However, keeping a record of the number of jumpers used can only be
done when you use the Loss Certification Wizard to configure the unit.
Note: If you have referenced your power meter to a source, connect the fiber
under test to the reference jumpers used for referencing.
