Polarization & Phase Control
The PFDP Passive Optical Fiber Depolarizer is an all-fiber device that converts polarized input into random polarization output, featuring ultra-fast response, low cost, high power handling, and no electrical power requirements. It employs multiple fiber couplers arranged in series to achieve polarization scrambling, where each coupler introduces changes in polarization due to slight birefringence variations and random phase shifts. The cumulative effect results in complex, non-deterministic polarization changes, effectively scrambling the input light.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
Passive Optical Fiber Depolarizer: >1nm Linewidth: Laboratory optical integration depends on preserving the optical budget through the complete path. The 1550nm, 1310nm, 1060nm, 980nm, 850nm, 780nm wavelength specification sets source and detector compatibility. The fiber/interface entry (PM1550, PM1310, PM1060, PM980, PM780, SM28, Hi1060, Hi980, 780HP) must match the connected components.

Technical FAQ
Input Fiber: PM1550, PM1310, PM1060, PM980, PM780, SM28, Hi1060, Hi980, 780HP · Fiber Protection: Bare, 0.9mm Tube. 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: 1550nm, 1310nm, 1060nm, 980nm, 850nm, 780nm. 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.
