With the introduction of the OP925 Continuous Wave RL and IL meter, you may be wondering what the difference is between this and the OP940. This video provides an overview of the different Return Loss test methods used by these systems: Continuous Wave Return Loss and Pulsed (OTDR) Return Loss. Explore the similarities and differences of these test methods and the systems that use them to help determine the solution that best fits your needs.
In this video, a receive cable is used to perform throughput insertion loss (IL) and return loss (RL) testing with the OP925 Continuous Wave RL and IL meter.
Next we’re going to look at testing the total IL and total RL of the DUT using the OP925.
To test insertion loss and return loss with the OP925 first power the instrument on. You’ll need a reference cord with a connector that’s similar to your DUT, also a matching block to terminate the end of the DUT.
Initially, the instrument starts up in OPM mode. To do dual wavelength measurements is usually easier just to cycle over to the dual wavelength IL and what we’re going to do is we’re going to perform a reference, and right now the instrument is referenced for IL.
We’re going to start by connecting up our reference cable, which historically with the rack mount 12 or 24 channel OP940 would require a fanout cable. But now with this in the compact size, we just have a straight MTP/MPO connector on the inside here and we’re going to mate a 12 fiber MPO to MPO cable straight to the front panel.
Lift the flap here and just connect that right up. And we’ll leave it there for now while we launch CLX.
