How to Do the FaultMap Test
Notes
The FaultMap test does not use the launch
compensation settings.
The FaultMap test uses the wavelength that gives
the best results.
Figure 69 shows the equipment for the FaultMap test.
1 Clean and inspect the connectors on the launch and tail cords
or patch cords and the link to be tested.
2 Connect the launch cord to the OTDR port and the link to be
tested, as shown in Figure 70. Connect a tail cord to the far
end of the link if necessary.
Or, you can use a patch cord that is 1 m long at minimum to
connect the tester to the link. To see results for the far-end
connector, connect a tail cord or patch cord (>1 m) to the far end
of the link.
3 On the home screen, tap the test setup panel.
4 On the CHANGE TEST screen, tap the button next to the
FaultMap test, then tap USE SELECTED. If a FaultMap test is
not available, tap NEW TEST to add one to the project.
5 Tap TEST or press .
