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.

Adjustments incrementing

Clock Source is set incorrectly.

Change Clock Source to “Recovered.”

CREATE REPORT

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.
