Quick Card
T-BERD®/MTS-2000 Test Set
E4100-series OTDR SMART TEST ASSISTANT
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-2000 and 4100-series OTDR module.
Equipment Requirements:
•T-BERD/MTS-2000 equipped with the following:
oFiber Optics Software Release V18.50 or
greater
oE4100 Series OTDR Module
•Fiber optic cleaning and inspection tools
•Launch Cable (minimum 20-meter Fiber optic
patch cable) with connectors matching the OTDR
port and Fiber Under Test
•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. Press the Home button to display the
Home view with the SMART TEST icon.
3. Tap the SMART TEST icon until it is yellow and
highlighted .
4. Select a configuration file:
•Select the EXPRESS configuration file to
setup the T-BERD for 5 second acquisitions
to quickly confirm loss and distance.
•Select the CERTIFICATION configuration file
to setup for 20 second acquisitions to
confirm loss and distance AND analyze all
events (slices, connectors, etc.)
•Tap to select a user configuration file
stored in the /disk/fiber/config folder.
5. Tap to view the SMART TEST Setup
screen.
6. Laser: Tap the desired wavelength(s) to test.
Select 2 wavelengths to detect bends.
7. Distance Unit: Tap the desired unit of
measure for the launch cable.
8. Launch Cable:
a. Tap YES if you are using a Launch Cable.
b. Tap the icon to enter or measure the
Launch Cable length.
c. If the launch cable length is known, tap to
clear existing text, enter new value on the
keypad and tap to return.
d. To measure the launch cable length, tap
Measure and tap Confirm. The measured value
will auto-populate when measurement is
finished.
Note: The Launch Cable should not be connected
to the Fiber Under Test during measurement.
9. Alarms: Choose User 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,
ensuring all fiber end faces are clean.
2. The T-BERD/MTS will perform acquisitions at the
configured wavelengths. Overall test results
(Pass or Fail) will be displayed in a pop-up
window. Tap the window to close it.
3. Results can be viewed in 2 formats.
Tap the softkey to toggle views.

Figure 9: Connection Check
•SmartLink view: The FUT is displayed as a
series of icons representing each event
(connector, splice, bend, etc.). The center of
the display (Link Table) 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 (Alarms) 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.
