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.
