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.
It is not uncommon for a tester to find themselves attempting to test return loss on an MTP connection, but find themselves unable to reference to the correct location. Sometimes this is due to dust or oil contamination or physical damage on the endface of the fiber, which can be corrected and prevented through proper care and maintenance.
