T-BERD®/MTS-5800 Modular Test Set
E4100 Module EXPERT OTDR Quick Setup
This quick card explains how to connect to a fiber under test, configure EXPERT OTDR test settings
using Quick Setup, run tests, and analyze results with a VIAVI T-BERD/MTS-5800 equipped with a 4100-
series OTDR module.
Equipment Requirements:
•T-BERD/MTS-5800 equipped with the following:
oFiber Optics Software Release V21.0 or
greater
oE4100 Series OTDR Module
•Fiber optic cleaning and inspection tools
•Launch Cable with connectors matching the
OTDR port and Fiber Under Test (a minimum
20-meter Fiber optic patch cable or leash is
recommended)
•Optical Coupler to connect Launch Cable to Fiber
Under Test
Figure 1: Equipment Requirements
The following information is required to complete the test:
•Type of Fiber (Multimode or Single Mode)
•Type of Connectors (SC UPC, SC APC, LC UPC, etc.)
•Cable Name or ID
•Fiber Name or ID
•Fiber Number
•Origin and Endpoint Locations Names or IDs
Fiber Inspection Guidelines:
•Use the VIAVI P5000i or FiberChek Probe
microscope to inspect both sides of every
connection being used (OTDR Port, Launch Cable,
bulkhead connectors, patch cords, etc.)
•Focus the fiber on the screen. If dirty, clean the
connector.
•If it appears clean, run inspection test.
•If it fails, clean the fiber and re-run inspection
test. Repeat until it passes.

Connect the Launch Cable to the OTDR port:
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.
Figure 3: OTDR Port Inspection
Connect to Fiber Under Test (FUT):
The OTDR may be connected to the FUT via an optical patch panel (OPP) bulkhead or coupler as
follows:
1. If the interface to the FUT is a patch cord, connect the patch cord to an optical coupler with the
same connector type.
2. Inspect the FUT connected to the coupler or OPP.
3. Inspect the fiber end face of the Launch Cable.
4. Connect the Launch Cable to the coupler or OPP.
Launch and Configure Test:
1. Press the Power button to start the test
set.
2. Tap the Fiber Optics icon in the
Status Bar at the top of the screen.
3. Tap the purple >on the left screen side
to display the Fiber Optics Home screen.
4. Tap the EXPERT OTDR icon until it is yellow
and highlighted .

5. Tap the Setup soft key .
6. 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.
7. Tap Alarms.
8. Set Alarm Level to Fail.
9. Set Threshold to Default, or select alternate
alarm thresholds (TIA-568.3, User, etc.)

Run Test:
•Press 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
end-face that fails the inspection test. Also,
inspect and clean the fiber end faces in any
patch panels or connectors near the OTDR.
After the connection check, the OTDR will
perform acquisitions at each selected
wavelength.
•The top section of the screen can be set to
display an Event line, or Trace Information by
tapping the toggle switch at the top right side
of the display.
•Results may be displayed in three formats:
SmartLink, Trace or Table.

Trace view:
•Graphical results for each wavelength or pulse
width are shown in different colors in center
display. Tap 1or 2to select the wavelength or
pulse width for results display.
•Distance, Loss, and Reflectance for the first
event is listed in the lower display. Swipe up to
see additional events. Values that violate loss
or reflectance pass/fail thresholds are shown
in RED.
•Tap the magnifying glass icons to zoom in ,
zoom out , or auto-zoom the display.
You can also pinch and zoom with your fingers.
Figure 8: Trace view
SmartLink view:
•The Fiber under test is displayed as a series of
icons representing each event (connector, splice,
bend, etc.). If there are more than 4 events, swipe
left to display additional icons.
Note: the icon-based view is not available if
Acquisition Mode = SmartAcq.
•In the center display, view summary results per
wavelength or pulse width for the entire span.
Acquisitions for which all events are acceptable are
marked with a green check . Acquisitions with
events that exceed pass/fail thresholds for loss or
reflectance are marked with a red .
•In the lower display, view each event that exceeds
thresholds.
•Tap on an event icon to the view detailed results
for the event.
Note: the icon-based view may not be available
on older T-BERD 5800s when acquisition Mode =
SmartAcq. Rerun the test with Manual or Auto
Acquisition or contact VIAVI to upgrade your unit
to add this feature.
