SKU: PFDP
The PFDP Passive Optical Fiber Depolarizer is an all-fiber solution designed to convert polarized input into randomly polarized output. It features ultrafast operation, low cost, high power handling, and requires no electrical power. Optimized for broadband lasers such as SLEDs, the device employs multiple segments of polarization-maintaining (PM) fibers spliced at specific angles to achieve efficient polarization scrambling. The input can be single-mode (SM) or PM fiber, while the output is always single-mode fiber, ensuring compatibility with a range of applications.
This depolarizer is highly effective in reducing polarization-dependent loss (PDL) and polarization mode dispersion (PMD) in optical communication test systems, eliminating artifacts in Optical Coherence Tomography (OCT), and stabilizing measurements in fiber sensing systems. However, it is not suitable for use with narrow-line lasers like Fiber Bragg Grating (FBG), Fabry-Perot (FP), or Distributed Feedback (DFB) lasers. The PFDP provides a passive, cost-effective solution for applications requiring reliable depolarization without the need for complex electronics.
