Retesting
Failed DUTs Laterwww.jgroptics.com

Situation
Use this procedure if:● You wish to perform a bidirectional test on a series of connector ends,continuing past any failures.
● After the full test, you wish to retest any fibers that failed (after, forexample, polishing the failed leads).

www.jgroptics.com

Configuration: DUT
Create a new DUT (Click ‘Add’). Fill out the Connectors and other fields,
making sure to set the Assembly Type to ‘Multifiber-to-Multifiber’ with
Number of Fibers set to 1. This will allow you to later redo individual fiberslater.
Example:When finished,click ‘Apply’

www.jgroptics.com

Configuration: Test
Create a Test (again, click ‘Add’) using your new DUT. In the example, wenamed our DUT “Simplex Bundle”.
Example:www.jgroptics.com

Measure
Go to the Measure tab and select your created test. In this example we called
it “Retry Failed”. Then click ‘Start’.

www.jgroptics.com

Settings
If some of the fibers fail later, you may receive a pop-up dialog box asking if
you want to retry those tests. This box can be turned off in the ‘Repeat Tests’section of the settings.

Measure
Perform your reference measurement for connector A.

www.jgroptics.com

Measure
After reference, make sure your Acquisition is set to ‘Measure’. Type in yourbundle serial number or name into the first ‘Serial Number’ text box, andtype ‘1’ into the second. This second text box will be your fiber number.

www.jgroptics.com

Measure
Connect each fiber, click ‘Start Single’, then click ‘Next DUT’. This will autoincrement the text box we are using as fiber number. Continue through all
the connector A ends of the whole bundle, whether the fiber passes or not.

www.jgroptics.com

Measure
When you get to the end of the bundle, you’ll want to test the other sideconnectors of the bundle (the connector B sides).
● Make sure you’ve clicked ‘Next DUT’ after the final fiber, because thisbutton also saves the results.
● You may now click ‘Second Direction’, which will discard yourConnector A reference and ask you to perform a new reference forconnector B.
● Do the new reference, then run through the same testing procedure asbefore, testing the fibers in the same order as last time. This will assign
the new Connector B results to the correct Connector A.
● Clicking ‘Next DUT’ after the last fiber will pop up a box saying there is
no more connector A data to match to. This means you’re done for thisbundle.

Notes
You may prefer to do many bundles’ connector A sides in a row, then run
through all the B sides, or do all of each bundle before switching to another.
Both are possible. Just type in the appropriate serial numbers whenswitching bundles. For example:● type Serial Number “Bundle1” and “1”● test through all connector A sides of Bundle1: Bundle1-1, Bundle1-2, ...
● type Serial Number “Bundle2” and “1”, repeat.
● When you wish to test the side B, simply click ‘Second Direction’ (andperform reference), and it should automatically rerun through the same
bundle serial numbers in the same order.

Notes
You may continue through failures for connector A, clicking ‘Next DUT’ andmeasuring other DUTs as much as you wish.

At any time you may
reconnect a previouslytested DUT to retest them.
Just manually enter the serial
number (both parts) of thetest you wish you to redo.

When you click ‘Next DUT’ your new values will replace the old ones.

ReportUse the Filter Builder in the Browser tab to find the results from all yourtests.
In this example, we filter on date, but you may wish select by other fields aswell: DUT type, Operator Name, etc.

www.jgroptics.com

ReportHere we see the results from our tests. This can be exported to excel orprinted out into a report using the buttons along the button.

www.jgroptics.com

Retesting
You may now retest any that you wish by connecting the appropriate fibers,
going back into the Measure tab, and typing in both parts of the Serial
Number for the fiber.
When you click ‘Next
DUT’ you’ll get a warningbox that you are
overwriting data. ClickYes!

ReportOnce you’ve retested the fibers you wish to, return to the Browser tab to see
the updated values in the report.

Tips for Using the Browser

www.jgroptics.com

Useful tips: Retrieving Only Failed Tests
To only return fibers that failed (so you don’t have to scan through a huge listof passes to find the fibers to retest), set up the filter selection criteria toselect fails.

www.jgroptics.com

Useful tips: Retrieving Only Failed Tests
Set your filter to return tests with the correct name and the failure
conditions. In this example we are looking for all failures: IL for connector Aor B, Reflectance for connector A or B.
Add conditions one at a time with
‘AND’ and ‘OR’, as appropriate.
When done, use the keyboard to add
brackets as shown so that theconditions are correctly implemented.
(must have correct name, and any
type of failure)
You should now click ‘Apply’ then‘Close’
www.jgroptics.com

Useful tips: Only Failure Results
Choosing the filter you just built should bring up a list of failures. You may
leave this list open in the ‘Browser’ while going back through the ‘Measure’
screen, so you can flip back and forth using it as a reference.

Adjusting Report Templateswww.jgroptics.com

Report Templates
When you have finished all your tests and export the results in a report, thedefault report templates will order your results by measurement time. Thismeans the fibers that were retested and overwritten later will appear out oforder in the report unless we alter the template.
Check the template filenames you are using in the Settings tab.

www.jgroptics.com

Report Templates
Open up the template file in C:\Program Data\JGR\MS12001\Templates\In our example it was ..\Report Extended.xml

www.jgroptics.com

Report Templates
If using VSReport designer, got to View > Grouping Window.
You may now drag and drop values to order by so Measurement Date is not
the first one. You may want to ‘Save As’ a newly named file, then select yournew report file in the MS12001 Settings tab.

www.jgroptics.com

Report Templates
If you don’t have VSReport, open the xml in Notepad or a similar text editor
and find the section for the report you use. Then cut-and-paste reorder the<Group> …. </Group> chunks of text to get the same result. Again, Save As
when done.
