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.

1. Tap the Setup soft key .
2. Tap Acquisition and configure the following
basic settings for the trace:
➢Laser: Choose the wavelength(s) to test.
➢Acquisition Mode:
oSelect Manual to manually to enter
Range and Pulse width settings.
oSelect Auto to automatically configure
Range, Pulse width, and SmartAcq
settings.
oSelect SmartAcq to perform an
acquisition with a short pulse width,
followed by an acquisition with a longer
pulse width. The first acquisition allows
events at the beginning of the fiber to be
detected more precisely.
➢Acq. Time: Select Realtime, Auto or the
desired time to sample the fiber.
➢Launch Cable: Select and enter Length
if you are using a Launch Cable.
Enter 20 meters or 66 feet for Viavi supplied

RUN TEST
1. Tap the Start soft-key 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. After connection checks, the OTDR will perform
acquisitions at the configured wavelengths.
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 4 events.
►The center of the 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 Manual or Auto
Acquisition or contact VIAVI to upgrade your
unit to add this feature.
