Measuring Insertion Loss and Return Loss using the front panel of the OP940

This video shows the basic functionalities of the OP940 Insertion and Return Loss Test Set. In this demonstration we measure an LC to LC cable assembly using the front panel of the OP940.

This video is intended to show the basic functionality of the OP940 Insertion and Return Loss Test Set. In this demonstration we will be measuring an LC to LC cable assembly.

First attach the reference cable to the source, making sure to inspect, clean if needed, inspect again, and connect.

Then, we will reference Insertion Loss and Return Loss. To reference Return Loss, select RL reference. With the reference cable open to air or connected directly to the detector, press “Start RL Ref”. The unit will display the reference value and distance from the front panel to the reference point. To set the RL offset, press the right button and select “Calc Zero”.

Once the Return Loss is referenced, press the “Home” button to return to the dual ILRL screen and select the IL Ref Option. Configure the reference cables for your insertion loos reference and, when ready, press “Start IL Ref”. When that is finished, press the “Home” button to return to the Dual ILRL screen and the test results will update in real-time.

Connect your device under test, between your reference cable and detector. Always make sure to inspect and clean if needed. Return Loss and Insertion Loss results are displayed. Select the “Pass/Fail” option to display the results color-coded based on the user-defined IL and RL pass-threshold settings.

Duplex LC Adapter – Testing Insertion Loss of cables terminated with Unibody LCs and LC connectors

The Duplex LC adapter is designed for testing insertion loss of cables terminated with Unibody LCs and LC connectors that are clipped together. The adapter screws on to any OptoTest 1mm and 3mm detectors making it ideal for implementing into new or existing test systems. It uses a magnetic interface to allow easy switching between the two LC connectors on a duplex cable.
