Quick Card
T-BERD®/MTS-5800 Modular Test Set
CWDM OTDR Smart Test Assistant
This quick card describes how to connect to a fiber under test and use the Smart Test Assistant to
configure test setups, run tests, and analyze results on a VIAVI T-BERD/MTS-5800 equipped with a
4100-series CWDM OTDR module.
The CWDM OTDR is meant to test a specific wavelength on a live Coarse Wavelength Division
Multiplexed (CWDM) network. Care must be taken to select and test the correct wavelength.
Equipment Requirements:
•T-BERD/MTS-5800 equipped Software
Release V18.0 or greater
•E4100 Series CWDM OTDR Module
(E41CWDMC10L, E41CWDM10U, or
E41CWDM8U)
•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 Connectors (SC UPC, SC APC, LC, etc.)
•Distance unit (feet, meters, miles, kilometers)
•CWDM Wavelength to be tested
Figure 2: E41CWDM OTDR Module
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 connector, patch cables, 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 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 if testing a live
CWDM System:
Figure 4: Connecting to Fiber Under Test
1. Inspect the OTDR port on top of the test set.
2. If the interface to the FUT is a patch cord, connect the patch cord to an optical coupler with the
same connector type.
3. Inspect the FUT connected to the coupler or OPP port.
4. Inspect the fiber end face of the Launch Cable.
5. Connect the Launch Cable to the OTDR port.
6. Inspect the other fiber end face of the Launch Cable.
7. Connect the Launch Cable to the coupler or OPP port.
8. Disconnect or disable the far end SFP on this wavelength.

Setup Test:
1. Press the ON/OFF button to turn on 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.
4. Tap the SMART TEST icon until it is yellow and
highlighted.
5. Select a configuration file:
a. Select the EXPRESS configuration file to
setup the T-BERD for a 5 second acquisition
to quickly confirm loss and distance.
b. Select the CERTIFICATION configuration file
to setup the T-BERD for 20 second
acquisitions to confirm loss and distance
AND analyze all events (splices, connectors,
etc.)
c. Tap to select a user configuration file
stored in the /disk/fiber/config folder.
6. Laser: If the wrong wavelength is selected,
tap to deselect. Tap and select the correct
wavelength to test.
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 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 must be at least
20m and must be disconnected from 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.

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 and will test the
configured wavelength. Overall test results
(Pass or Fail) will be displayed in a pop-up
window. Tap the window to close it.
2. Results may be viewed in 2 formats.
Tap the Trace/SmartLink soft key to toggle
between views.
•SmartLink view: The FUT is displayed as a
series of icons representing each event
(mux/demux, connector, splice, etc.).
▪The center 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 events that exceeds
alarm thresholds.
▪Tap an event icon and tap the Event View
soft key to show detailed results for the
event.
•Trace view: Graphical results for the
wavelength are shown in the upper display.
Use the following controls to change the
display:
▪Toggle between single event and
multiple event view in lower screen.
▪Tap the Zoom soft key to enable the
following controls:
•Toggle between auto zoom and
full trace view.
•Expand and contract trace.
3. Repeat steps 1 and 2 for all wavelengths and
fibers under test being careful to check and
double check the wavelength to be tested.
