SKU: PFDP
The PFDP Passive Optical Fiber Depolarizer is an all-fiber device that converts polarized input into random polarization output, offering ultra fast, low cost, high power handling, and requiring no electrical power. Optimized for broadband lasers like SLEDs, it comprises multiple segments of polarization-maintaining (PM) fibers spliced at precise 45° and 90° angles. The cumulative effect of these splices results in efficient polarization scrambling, making it ideal for passive, cost-effective depolarization without complex electronics. It is particularly effective in reducing polarization-dependent loss (PDL) and polarization mode dispersion (PMD) in optical communication systems, eliminating artifacts in Optical Coherence Tomography (OCT), and ensuring stable measurements in fiber sensing systems.
The device accepts single-mode (SM) or PM fiber inputs, with a single-mode output. However, it is not suited for narrow-line lasers like Fiber Bragg Grating (FBG), Fabry Perot (FP), and Distributed Feedback (DFB) lasers.
