Quick Card
T-BERD®/MTS-5800 Modular Test Set
E4100-series OTDR SMART TEST
This quick card describes how to connect to a fiber under test, configure SMART TEST OTDR settings,
run tests, and analyze results with a VIAVI T-BERD/MTS-5800 and 4100-series OTDR module.
Equipment Requirements:
• T-BERD/MTS-5800 equipped with the following:
o Fiber Optics Software Release V17.22 or
greater
o E4100 Series OTDR Module
• Fiber optic cleaning and inspection tools
• Launch Cable with connectors matching the
OTDR port and Fiber Under Test (a 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.)
• Distance unit (feet, meters, miles, kilometers)
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 Launch Cable to OTDR port:
1. Inspect the OTDR port on top of the test set.
2. Inspect the fiber end face of Launch Cable.
3. Connect Launch Cable to the OTDR port.

Launch and Configure Smart 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 Home icon to display the Home
view with the SMART TEST icon.
4. Tap the SMART TEST icon until it is yellow and
highlighted .

5. Select the Point_To_Point configuration file and
tap to view the SMART TEST Setup
screen.
Figure 4: SMART TEST Configuration File
6. Laser: Tap the desired wavelength(s) to test.
Select 2 wavelengths to detect bends. Selected
wavelength(s) will turn dark blue.
7. Distance Unit: Tap the desired unit of measure
for the launch cable.
8. Launch Cable:
• Tap YES if you are using a Launch Cable.
• Tap the icon to enter or measure the Launch
Cable length.
• If the launch cable length is known, tap to
clear existing text, enter new value on the keypad
and tap to return.
• To measure the launch cable length, tap Measure
and tap Confirm. The measured value will autopopulate when measurement is finished.
• Note: The Launch Cable should not be connected
to the Fiber Under Test during measurement.
9. Alarms: Choose Default for Viavi recommended
Pass/Fail limits.
10. Distance Unit: If you wish to use a different unit of
measure for the test results, change the unit of
measure to the desired value.

Connect to Fiber Under Test (FUT):
The Launch Cable may be connected to the FUT
via an optical patch panel (OPP) or an optical
coupler:
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 other fiber end face of the Launch
Cable.
4. Connect the Launch Cable to the coupler or OPP.

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,
repeat steps 1 through 3 on page 1, and repeat
steps 1 through 4 above on page 3.
2. The T-BERD will perform acquisitions at the
configured wavelengths.
3. Results can be displayed in 2 different formats:
Trace view or SmartLink view. Tap to
toggle between views.
Figure 9: Connection Check
• SmartLink view: The FUT is displayed as a
series of icons representing each event
(connectors, splices, bends, etc.). The center
of the display shows summary results 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 . The lower display
shows each event that exceeds thresholds.
Softkeys can be used to alter the display:
• Tap any icon in the upper display to
show detailed results for the event.
• Detailed results are shown for all
events.

• Trace view: Results for each wavelength are
shown in different colors in the top section of
the display. Each event is listed in the lower
section of the display. Any events that violate
pass/fail thresholds for loss or reflectance are
shown in RED.
Use the right and left arrow keys in the
control panel to Toggle between results for
each wavelength. Tap the Zoom soft key
to enable the following zoom controls:
• Toggle between automatic zoom and
full trace view
• Expand and contract trace.

4. Tap the Save softkey to view File
Recording Information.
5. Enter Fiber Id, Fiber Number, Locations, and Job
ID as follows:
• Tap field to open keyboard
• Tap to clear existing text.
• Enter desired value.
• Tap icon to return.
Note: The Job ID field identifies the Job ID and
creates a folder to save the result by the same
name. The default save location is JOB folder
under disk.
6. Tap to save the OTDR trace in .sor
format. Tap to save OTDR trace in .sor
and .pdf format. One file is saved per
wavelength.
