Measuring Optical Power with MFP
It is important to keep all optical connections and surfaces clean to ensure accurate
measurements and operation. Always clean all test jumpers before conducting tests.
1. Turn On the MFP and verify that it is in regular test mode. If MFP is in the Fiber
ID mode, press the Fiber ID button to switch to the regular power meter mode.
2. Select the appropriate fiber optic test jumper. The fiber type of this jumper must
be the same as the fiber type normally connected to the output being measured.
3. Mount the appropriate adapter cap on the MFP port. This adapter cap must
match the connector on the end of the test jumper you will connect to the MFP.
4. Connect one end of the test jumper to the MFP adapter cap and the other end to
the optical output to be measured.
5. Press [ ] to select wavelength that matches the nominal wavelength of the
source being measured.
6. Press [dB/dBm/µW] to display power in [dBm] or press and hold to display power
in [µW].
