The MS12 Return Loss Module combines advanced time-domain technology with a built in unique wide aperture integrating cavity. An internal monitoring feature maintains laser stability for reliable insertion loss testing throughout an entire working day. The internal return loss reference helps with highly accurate multimode and single-mode return loss measurement performance. The multimode MS12 Return Loss Meters meet IEC-61280-4-1 Encircled Flux Standard.
The EXFO IQS-3250B and IQS-9403 are fully compatible with the MS12001 line. They meet the same specifications and will be recognized by both the MS12001 and the IQS-12001B systems.
