At Fiber Optic Center, we recommend the Viavi MAP-200 Passive Component Tester to measure IL/RL. Viavi (formerly JDSU) has been producing IL/RL meters for at least 20 years.

In fact, they initially built this tester for their own internal use, because suitable equipment was not available for the new products they were developing.

This company’s experienced team (of which I was once a part) continually improves this highly reliable instrumentation. My customers and I find that it has all the tools you need, and Fiber Optic Center will help you get the best out of it. In fact, this is my promise to my customers: When you buy test equipment from us, I’ll make sure you succeed at using it.
