The HP 11896A Polarization Controller adjusts polarization and not power. Its optical fiber loop design provides all states of polarization with extremely small optical insertion-loss variations (±0.002 dB) over a wide spectral range (1250 to 1600 nm). This performance combination maximizes measurement accuracy for power-sensitive applications like polarization-dependent loss and gain. This is because the measurement uncertainty contributed by the polarization controller is minimized. Specifications. Operating Wavelength Range: 1250 to 1600 nm. Overall Insertion Loss: <2.0dB. Insertion Loss Variation (with adjustment/rotation): < ± .002 dB (Option 025). Polarization Extinction Ratio: > 40 dB. Polarization Adjustment Resolution: 0.18° (180° /1000 encoder positions). Angular Adjustment Accuracy: Minimum step size, ±0.18°; Greater than minimum step size, ±0.18°. Optical Port Return Loss: > 35 dB. Option 025: One meter fiber extender with FC/PC connector interfaces.

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.
