PER-Analyzer

Keysight’s N7782B series of PER-Analyzers has been designed for high-speed and highly accurate testing of the polarization extinction ratio (PER) in PM fibers. The polarimetric measurement principle guarantees reliable measurements of PER values of up to 50dB. The real-time measurement capability in combination with automation interfaces makes this unit ideally suited for integration in manufacturing systems, for example, pig-tailing stations for laser diodes and planar waveguide components. Analog interfaces are provided for the integration of the system in control loop applications.Key Benefits：Accurate polarization extinction ratio measurements in PMF, up to 50 dBUses the full polarimetric method recommended for aligning PMF with laser signalsSupports automated test with N7783B thermal cycling units for fiber stressingEasy to use graphic software with real-time display
