SONET Bit Error Rate Testing (BERT)
This quick card describes how to configure and run a SONET Bit Error Rate Test at the full
concatenated line rate. Please note that the OneAdvisor can also test channelized payloads
(DS1, VT1.5, and STS-n). Please refer to the OneAdvisor User’s Guide for information.
LAUNCH TEST
1. Press the Power button to turn on the
OneAdvisor.
2. Press the 100G Module Test icon
at the top of the screen.
3. Tap the Power button and click
to launch the 100G Module.
4. Using the Select Test menu, Quick Launch
menu, or Job Manager, launch the SONET
Bulk BERT test on Port 1 for the desired
Optical Carrier level. For Example:
SONET►OC-3►STS-3c Bulk BERT►P1 Terminate.
5. Tap to open the Tools Panel and
select .
6. Press to continue.

CONFIGURE TEST
•The followingInformation is needed to
configure the test:
•Optical wavelength
(typically, 1310nm or 1550nm)
•Test Pattern(s) (default is 2^23-1 ANSI)
•BER Pass/Fail Threshold
1. Press the Setup soft key on the top
right side of the screen.
2. Select the Interface/Connector folder.
3. Insert desired SFP into the Port 1 SFP+ slot
on the top of the 100G Transport Module.
4. Review SFP information in the Connector
tab:
►Verify that the SFP operates on the
required wavelength (1310nm or
1550nm).
►Verify that the SFP supports the
required optical carrier level (OC-3,
OC-12, OC-48, or OC-192).
►Note the Min and Max Tx Levels (dBm)
and Max Rx Level (dBm) to assess if
optical attenuators are required.
5. Select the indicated folders and configure
your test as follows. Leave all other values
at default, unless specified in the work order.
6. Press the Results soft key to view the
Test Results screen.

RUN TEST
1. Using drop-down menus , select
“Payload/BERT” for the right results display.
2. Select the Laser tab in the Actions panel,
and press . The button will turn yellow
and be relabeled .
3. Press the Restart soft key .
4. Verify the following:
►Level (dBm) is within the Rx Level range
of the SFP.
►Summary LED is green.
►Signal Present LED is green.
►Frame Sync LED is green.
►Path Pointer Present LED is green
►Pattern Sync LED is green.
►Summary/Status results shows ‘ALL
SUMMARY RESULTS OK”
5. Allow the test to run for desired duration and
verify the following:
►Bit/TSE Error Rate result does not
exceed your required threshold.
(0.00E+00 if pass/fail threshold unknown)
CONNECT TO LINE UNDER TEST
•Use the VIAVI P5000i or FiberChek Probe
microscope to inspect both sides of every
connection being used (SFP, attenuators, patch
cables, bulkheads)
►Focus fiber on the screen.
►If it appears dirty, clean the fiber end-face
and re-inspect.
►If it appears clean, run inspection test.
►If it fails, clean the fiber and re-run inspection
test. Repeat until it passes.
•If necessary, insert optical attenuators into the
SFP TX and/or RX ports.
•Connect the SFP to the port under test using a
jumper cable compatible with the line under test.

Status Tip
Signal Present LED
not green
Check your cables. Tx and Rx may be
reversed.
Path Pointer Present
LED not green
and AIS-P alarm on
There may be no loop or no connectivity to
the loop. The wrong payload may be
selected (concatenated vs. channelized).
RDI-L alarm on
The Tx Level is too high.
Add an attenuator between the SFP Tx port
and the line under test.
Path Pointer
Adjustments incrementing
Clock Source is set incorrectly.
Change Clock Source to “Recovered.”

6. In the 100G Module’s Quick Config menu,
change “Pattern” to the next value in the test
plan.
7. Press the Restart soft key to reset results.
8. Allow test to run for desired duration and verify
the following:
►Pattern Sync LED is green.
►Bit/TSE Error Rate or Round Trip Delay
does not exceed your required threshold.
►Repeat steps 6 through 8 for all Patterns
in the test plan. Patterns may include:
•Delay: Measures Round Trip Delay
(RTD) instead of Bit Errors.
RTD values are shown instead of BER
in the “Payload/BERT” results display.
