QUICK CARD

►Use the VIAVI P5000i or FiberChek Probe

microscope to inspect both sides of every

connection being used (OCC Port, Launch

Cable, bulkhead connectors, patch cables, etc.)

►Focus fiber on the screen. If dirty, clean the

end-face.

►If it appears clean, run inspection test.

►If it fails, clean the fiber and re-run inspection

test. Repeat until it passes.

CONNECT TO FIBER UNDER TEST (FUT)

All fibers and connectors should be inspected and

clean prior to connection, as described on page 1.

The OTDR may be connected to the FUT via an

optical patch panel (OPP) or a coupler:

1. Inspect the OTDR port on top of the test set.

2. Inspect the fiber end face of the Launch Cable.

3. Connect the Launch Cable to the OTDR port.

4. If the interface to the FUT is a patch cord,

connect the patch cord to an optical coupler.

5. Inspect the FUT connected to the coupler or

OPP port and the fiber end face of the Launch

Cable.

6. Connect the Launch Cable to the coupler or

OPP port.

RUN TEST

1. Tap to start the test. After auto-

configuration, the OTDR will perform a

connection check to ensure that the connection

is Good. If the Connection is Bad, disconnect

the launch cable, and reconnect as described

on pages 1 and 2, cleaning every fiber end-face

that fails the inspection test.

2. The OTDR will perform acquisitions at the

configured wavelengths. Overall test results

(Pass or Fail) will be displayed in a popup

window. Touch the popup window to close it.

3. Tap the SmartLink tab at the left screen top to

select SmartLink view.

4. Set the toggle switch at the right screen top to

Event Line.

5. View SmartLink results:

►The FUT is displayed as a series of icons

representing events (front connector,

launch cable, connectors, splices, bends,

etc.) and distances. Swipe left or right to

view additional icons on spans with more

than 5 events.

►The lower display shows summary results

for the entire span for each acquisition or

wavelength. Tap any event in the upper

display to view detailed results for that

specific event.

►Events and Acquisitions are marked with a

green check or red xbased on the Alarms

setting.

Note: the icon-based view may not be

available on older T-BERD/MTS 4000s when

acquisition Mode = SmartAcq. Rerun the test

with the CERTIFICATION_AutoTest_20s

configuration file or contact VIAVI to upgrade

your unit to add this feature.
