Quick Card
T-BERD®/MTS-2000 Modular Test Set
E4100 Module FTTH OTDR
This quick card exxplains how to connect to a fiber under test, configure FTTH mode test setups, run
tests, and analyze results with a VIAVI SmartOTDR or T-BERD/MTS-2000 and 4100-series OTDR module.
Equipment Requirements:
•SmartOTDR or T-BERD/MTS-2000 equipped with the following:
oFiber Optics Software Release V16.22 or greater
oE4100 Series OTDR Module for T-BERD/MTS-2000
oFTTH-SMARTLINK Mapper icon-based OTDR
results option (FTTH-SLM license key required)
•Fiber optic cleaning and inspection tools
•20-meter (or longer) fiber optic patch cord (Launch Cable)
•Optical Coupler to connect Launch Cable to Fiber Under Test
The following information is required to complete the test:
•Type of Connectors (SC UPC, SC APC, LC UPC, etc.)
•Distance unit (feet, meters, miles, kilometers)
•LOCATION: FTTH OTDR testing must be done from ONT to OLT direction. It can be either the
Second Splitter, NAP or at the Customer Premise (ONT Location)
Fiber Inspection Guidelines:
Inspect and clean (if necessary) both sides of every connection being used (bulkhead connectors, patch
cords, and OTDR port) prior to reconnection for each test. Using the P5000i or FiberChek Probe:
•Focus fiber on the screen. If dirty, clean the connector.
•If it appears clean, run inspection test.
•If it fails, clean fiber and re-run inspection test. Repeat until it passes.

Connect to Fiber Under Test (FUT):
All fibers and connectors should be inspected prior to connection, as described on page 1. The OTDR
may be connected to the FUT via an optical patch panel (OPP) bulkhead or an optical coupler as
follows:
Figure 3: Connecting OTDR to FUT via Coupler or OPP
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.
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.
Launch and Configure Test:
1. Press the ON/OFF button to turn on the test set.
2. If files are to be saved, tap the FILE Button and tap the results folder. Otherwise,
proceed to step 4.

3. Tap the Create Directory soft key, enter a name for your new folder, and tap the Enter
key. All trace files will be saved to this directory.

5. Tap the FTTH OTDR icon until it is selected and highlighted in yellow.
6. Press the RESULTS button to show the Results view.
7. Press the SETUP button.
8. Tap the FTTH (PON) Setup soft key to configure your GPON testing Scenario:
Figure 6: FTTH (PON) Setup Screen
a) Laser
i) For GPON Network Construction: Select 1310/1550nm or ALL.
ii) For GPON Live Network Testing (Live): Select 1625nm (LIVE) (or 1650nm if
available). 1625nm and 1650nm wavelengths allow for live network testing
without interfering with the live traffic between the OLT and ONT.
b) Direction: Always select ONT to OLT.

c) Number of Splitters: Select one of the following modes:
i) 1 / 2 / 3: If you know the topology of your network under test, select 1if you
don’t have cascaded splitters; select 2 or 3 if you have a cascaded splitter
topology.
ii) Discover: If you do not know the network topology, select Discover. The OTDR
will automatically detect how many splitters you have in your network and try to
detect the type of splitter. Note: Pass/Fail analysis is disabled. The
measurement is based on the attenuation values and the distances between
splitters: If two splitters are within the specified Splitter Dead Zone (SDZ), the
OTDR may show the two splitters as one single event.
d) Launch Cable End and Receive Cable Start: Select Length if you want to see the
Launch cable as a dedicated event with no measurements. After selecting Length,
specify the length of your Launch or Receive Cable. Otherwise, select No.
e) Distance Unit: Select between meter, km, feet, kfeet, miles or inches.
9. ALARMS Menu: Tap the Alarms soft key to configure any alarm thresholds: Selections
available are: ITU or IEEE G.PON Standards based alarms, TIA/ISO-IEC Structured Cabling
Alarms or User Defined Alarms.

10. Link Menu: Tap the Link soft key to change your Labeling and Fiber Increment
configurations, in order to automate file naming when saving reports.

Run Test:
1. Tap the RESULTS button.
2. Tap the START/STOP button 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, repeat steps 1 through 7
on page 2. Also, inspect and clean the fiber end faces in any patch panels or connectors near the OTDR.
3. The OTDR will perform acquisitions at the configured wavelengths. Results may be displayed in 3 different
formats: Trace view with Summary, Trace view with events, or Smartlink view.
•Tap the Trace/Smartlink soft key to toggle between Trace views and SmartLink view.
•Tap the Enter button in the center of the arrow buttons to toggle between the
Trace view with Summary and Trace view with Events:
a. Trace view with Summary: Results for each wavelength
are shown in different colors in the upper results display.
Fiber length and link loss are shown in the lower display.
•Use the right and left arrow buttons to toggle
between results for each wavelength.
b. Trace view with Events: Results for each wavelength
are shown in different colors in the top of the display.
Each event is listed in the lower display. Events that
violate pass/fail alarm thresholds are shown in RED.
•Use the right and left arrow keys to toggle between
results for each wavelength.
•Tap the Zoom soft key to enable the following
controls:
▪Toggle between auto zoom and full trace view.
▪Expand and contract trace.
c. SmartLink view: The FUT is displayed as a series of icons
representing each event (connectors, splices, splitters,
bends, etc.). The center of the display shows summary
results per wavelength 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.
•Tap an event icon and tap the Event View soft
key to show detailed results for the event.
