The Advantest Q8163 Optical Polarization Scrambler randomizes the polarization state of light across the entire Poincaré sphere, enabling accurate measurement of polarization-dependent loss (PDL) in optical components and subsystems. Operating continuously at high speed with minimal insertion loss fluctuation, the Q8163 delivers precise polarization control through fiber-based scrambling elements. Its low-loss architecture and deterministic polarization variance make it ideal for characterizing optics with small PDL values and for integration into polarization measurement, stabilization, and emulation systems.

– Compatibility & Integration
The Q8163 interfaces via FC-PC connectors and supports GPIB remote control. Design requires horizontal operation with adequate clearance around air vents for cooling fan function. Store horizontally; vertical storage requires stability measures. Avoid rapid temperature changes, mechanical shock, vibration, moisture, dust, and external magnetic fields during operation and storage.
