Polarization & Phase Control
The FPOL Series All-Fiber Polarization Controllers are constructed from a single continuous optical fiber routed through four independently stepper motor–driven loop paddles. Each paddle functions as a rotatable waveplate, enabling full-range polarization control with ultra-low insertion loss, broad wavelength compatibility, and high optical power handling. Each fiber loop introduces controlled stress and rotation, leveraging birefringence modulation and geometric phase effects to precisely manipulate the polarization state of light. This all-fiber design ensures inherently broadband operation across transmitted wavelengths, with only minor wavelength dependence due to birefringence characteristics. The FPOL system can operate as either a polarization controller or a polarization scrambler.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
Fiber Polarization Controller – 0.5dB Loss, 2Hz, USB: Laboratory optical integration depends on preserving the optical budget through the complete path. The 488, 532, 650, 780, 850, 980, 1060, 1310, 1550, 2000 wavelength specification sets source and detector compatibility. The fiber/interface entry (SMF-28, SM450, 460HP, SM600, 780HP, SM800, Hi1060, SM1950, PM400, PM460, PM630, PM780, PM850, PM980, PM1550, PM1950) must match the connected components.

Technical FAQ
Fiber Type: SMF-28, SM450, 460HP, SM600, 780HP, SM800, Hi1060, SM1950, PM400, PM460, PM630, PM780, PM850, PM980, PM1550, PM1950 · Connector: FC/APC, Special. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength: 488, 532, 650, 780, 850, 980, 1060, 1310, 1550, 2000. Check the Polarization & Phase Control passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
