The HP 8169A Polarization Controller provides polarization synthesis relative to a built-in linear polarizer. The internal quarter-wave plate and half-wave plate are individually adjusted to create all possible states of polarization. Predeterministic algorithms within the HP 8169A enable the transition path from one state of polarization on the Poincare sphere to another to be specified along orthogonal great circles. These features are important because device response data can be correlated to specific states of polarization input to the test device. Specifications. Operating Wavelength Range: 1470 to 1570 nm. Overall Insertion Loss: < 1.5 dB (Option 020). Insertion Loss Variation (with adjustment/rotation): <= ± 0.03 dB (Option 020).

The UC INSTRUMENTS GM8015 Motorized Polarization Scrambler is a programmable motorized control polarization scrambler. Its polarization control capability enhances measurement speed, accuracy, and overall productivity. The continuous long optical fiber enables high power and ultralow insertion loss. This design provides a wide range of AutoScan rates and high incremental angular resolution. Four fiber knob loop design has proven to permit excellent control with ultra-low power variations (leading to low PDL). This reliable design allows a wide range of applications from component testing to PMD related activities. Features. Single-fiber design. Ultra-low insertion loss, PDL, and back-reflection. Convenient save/recall settings. Multi-rate polarization scrambling. AutoScan operation with a wide dynamic range of rotational speed. RS232 interface. Specifications.
