OneAdvisor ONA-800
FTTA OTDR, Cell Tower Construction and Maintenance
This quick card explains how to connect to a fiber under test, configure Fiber to the Antenna (FTTA) OTDR
test setups, run tests, and analyze results with a VIAVI ONA-800 equipped with a 4100 series OTDR.
Equipment Requirements:
•ONA-800 equipped with the following:
oFiber Optics Software Release V19.92 or
greater
oE4100 Series OTDR Module
oSoftware options for FTTA OTDR and
SmartLink Mapper (SLM) icon-based OTDR
results
•Fiber optic cleaning and inspection tools
•20-meter fiber optic patch cable (Launch Cable)
with connectors that match the OTDR Port and
Fiber Under Test (SC UPC, SC APC, LC UPC, etc.)
•Optical Coupler to connect Launch Cable to
BBU Jumper Cable or Trunk Cable
Figure 1: Equipment Requirements
The following information is required to complete the procedure:
•Type of Fiber (Multimode or Single Mode)
•Type of Connectors (SC UPC, SC APC, LC UPC, etc.)
•Tower architecture:
oIs there a BBU jumper cable?
oIs there an RRU jumper cable?
•RRU and BBU/Base Station IDs
•Fiber Code (1-Rx, 1-Tx, …, 24-Tx)
Fiber Inspection Guidelines:
•All fiber end-faces must be clean and pass an
inspection test prior to connection.
•Use the VIAVI P5000i or FiberChek Probe
microscope to inspect both sides of every
connection being used (SFP Port, bulkhead
connectors, patch cables, etc.)

Connect to Fiber Under Test (FUT):
All fibers and connectors should pass fiber inspection prior to connection, as described on page 1. The
OTDR may be connected to the FUT as follows:
Figure 3: Tower Architecture with BBU Jumper Figure 4: Tower Architecture, no BBU Jumper
1. Inspect and clean the OTDR port on top of the test set.
2. If the interface to the FUT is the BBU Jumper or Trunk Cable, connect the cable to an optical coupler
with the same connector type.
3. Inspect and clean the FUT connected to the coupler or Optical Patch Panel (OPP).
4. Inspect and clean fiber end face of the Launch Cable.
5. Connect the Launch Cable to the OTDR port.
6. Inspect and clean the other fiber end face of the Launch Cable.
7. Connect the Launch Cable to the coupler or OPP leading to the RRU.

7. Navigate to the ONA-800/disk/config/FTTA folder.
8. Select FTTA_RRU_Maintenance.SM-OTDR for testing to an RRU at the far-end, or
Select FTTA_RRU_ConstrLoop.SM-OTDR for testing to a loopback at the far-end.
9. Tap the and tap soft key to display FTTA OTDR Setup.
Figure 5: Setup
10. Configure Analysis settings as follows:
•Set BBU Jumper to Yes if there is a BBU Jumper Cable between the Launch Cable and OVP;
Set BBU Jumper to No if the Launch Cable is directly connected to the OVP.
•Set RRU Jumper to Yes if there is a Junction Box/OVP at the top of the tower between the Trunk Cable and
RRU; Set RRU Jumper to No if there is no Junction Box or no RRU Jumper.
•Leave other settings at default values.
11. Configure Link Description settings as follows:
•Set Base Station ID to the Base Station or BBU Identifier.
•Set RRU ID to the RRU Identifier or sector (Alpha, Beta, Gamma).
•Set Fiber Code to the fiber number and polarity using the up and down arrows.
•Set Change Fiber Nbr to Increment.
•Set Distance Unit to feet or meter.

Run Test:
Press the icon to start the test. The OTDR will perform an auto-configuration, Connection Check, and
Acquisition on each wavelength. If the Connection is Bad, repeat steps 1 through 7 on page 2, to ensure
the patch cable is clean and undamaged. Results will be auto-stored to the current directory.
View Results:
Result may be displayed in 3 different formats: SmartLink, Trace, or Table. The view is selected at the top
of the display.
Figure 6: View selection
•SmartLink view:
oIn the upper display, the FUT is displayed as a series of icons representing events (end-of-fiber,
launch cable, connector, etc.). Swipe left to display additional icons/events.
oThe center of the display shows summary results per wavelength. Acquisitions for which all events
are acceptable are marked with a green check.
oTap on any icon to display event type and pass/fail status and to label each icon according to your
tower architecture, in the lower display:
▪BBU: Connection (coupler) between launch cable and BBU Jumper Cable
▪BOT TWR: Optical Patch Panel at bottom of tower
▪TOP TWR: Junction Box/Patch Panel at Top of tower
▪RRU: End of RRU Jumper Cable

oResults 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.
oTap the icon to Auto-zoom the trace.
oTap 1 or 2 at the top of the display to toggle between results for the two wavelengths.
