The JDSU MAPV+2B Multiple Application Platform (MAP) Variable Backreflector Cassette series provides precise levels of return loss (RL) to transmitters, which allows measurements of system sensitivity or system degradation as a function of backreflection. When used with a transmitter/receiver pair and characterization equipment, the backreflector can be used to establish the magnitude of reflections that significantly degrade transmission system performance, and to characterize the problems they cause. The backreflector uses JDSU's linear attenuator prism and high reflectivity mirror to precisely control the level of RL. The cassette is available in single-mode (SM) or multimode (MM) fibers and with an optional coupler for monitoring. Key Features. 0.01 dB resolution. Operation at 850/1310 or 1310/1550 nrn. SM or MM fiber. Applications. Transmitter/receiver development and testing. Reflection testing for connectors. Quality assurance acceptance testing. Laser development and production.
