Test Procedure for SC-LC Hybrid Cables(OPL-PRO 930)
Overview
Testing duplex cables with unlike connectors can be both time consuming and messy without the proper procedure.
The following test procedure will show how to best test duplex cables with unlike connectors—in this case, LC-SC—
as well as having an organized and in-depth test report created through OPLPro 930 software.

Test Procedure for LC-SC Duplex Cables (OPL-PRO)NE W

Upon first switching on the OP930, it must have 10-15 minutes to warm up. During this warm-up time, verify thatthe OPM adapter is a universal 1.25mm adapter for referencing LC cables. This is because the duplex LC-SC DUT
will test the SC endfaces first thus having the LC endfaces initially connected to the reference cable. Connect theFC/APC-FC/APC saver cable to the OP930 front panel connectors. Next, connect the FC/APC-LC/PC reference
cable to the saver cable.
EWNSetup

Start up the OPL-PRO930 software either
through the Start menu or the shortcut on
the desktop. To set up the serial number,navigate to Setup > Options and in theMeasurement Setup tab, verify theAlphanumeric (32 char) option in the Serial
Number Configuration is checked. Clickclose to exit and save these settings.
To enter header data, click Enter DataHeader. A popup screen will allow the user
to make any necessary header changes tothe test report. Click Save and Close whenfinished making changes. The information
will be automatically added to the Data file.

Verify that the correct Setup file, Parameter
file, and Configuration are selected. Note that
if using a Multimode system that the proper
MMF configuration is selected.

If a change is made, the user will be prompted
to re-reference as shown in figure 3.
Otherwise, click Ref.

AN-108

Testing the LC Side of the Duplex Cable
Reference
The user will be prompted to take an RL
Reference. With the reference cable’s LCendface unmated, click Next to begin. The
software will search for the largest reflection
and Edisplay
the power for both wavelengths
N W
as well as the approximate position.

Figure 4: RL reference prompt

The next popup screen will prompt the user to prepare for
an insertion loss reference. Connect the unmated endface
to the 1.25mm OPM adapter and click Next. Then, connect
the 2.5mm adapter to the OPM to accommodate the SC
connector of the cable under test.
Figure 5: Insertion Loss Reference prompt

Serial Number Setup
Click on the Serial Number text to the Serial Number Entr y edit box. Here, the user is able to add pre- and postfix indicators for the serial number. For example, connector type as well as channels can be designated (LC or SC;channel A or B). This is also configured for up to 32 alphanumeric characters. When finished, click OK.

Figure 6: Serial number display and edit box

Testing
Connect the first of the LC/PC endfaces of the DUT (LC1) to the LC
end of the reference cable and click Test. For the initial test, the user
will be prompted to create a Data file.
If an existing data file is going to
be used, remember to append thedata to avoid losing any previous
information. Every other test after
this will append data to the selected
data file so this step will not need tobe performed again.

Figure 7: Showing if using an existing file you need to append the data

After the user has chosen whether or not to append the data, actual testing of DUT will begin. When the test has
finished and passed, change to LC2 endface, edit the serial number to specify proper endface, pre-fix, post-fix,etc., and click Test.

Test Procedure for SC-LC Hybrid Cables(OPL-PRO 930)

AN-108

Testing the SC Side of the Duplex Cable
When switching to the SC testing, make sure that the 2.5mm OPM adapter in connected to the detector. Also, a new
FC/APC-SC/PC reference cable must be used to test the SC endfaces of the DUT. Because of the new reference
cable, insertion loss and return loss should be re-referenced before testing the cables.
NE W

Reference
N E W the cables are reconfigured for theWhensecond half of testing, press the Ref button.
As before, the user will be prompted to takean RL Reference. With the reference cable’s
SC endface unmated, click Next to begin.

Figure 8: RL reference prompt

Figure 9: Insertion Loss Reference prompt

The next popup screen will again prompt the user toprepare for an insertion loss reference. Connect theunmated SC endface to the 2.5mm OPM adapter andclick Next. After the reference is done, connect the1.25mm adapter to the OPM to accommodate the LC
connectors of the cable under test.

Testing
After making sure that the serial number properly specifies the endface, pre-fix, post-fix, etc., connect the firstof the SC/PC endfaces of the DUT (SC1) to the SC end of the reference cable and click Test. When the test has
finished and passed, change to SC2 endface, edit the serial number to specify proper endface, pre-fix, post-fix,etc., and click Test.
