All Fiber Optic Piezoelectric Polarization Scrambler/Depolarizer

SKU: AFPS

The AFPS series of All-Fiber Optical Polarization Scramblers is designed to randomize the polarization states of fiber with desirable features, including ultralow insertion loss, broad bandwidth, compatibility with all fiber types, and high power handling capabilities. This technology is achieved by applying controlled stresses to the passing fiber using four to six piezoelectric squeezing plates arranged at 45-degree angles sequentially, inducing fiber birefringence phase retardation. Consequently, the device rapidly converts any input polarization state into randomly polarized states, covering the entire Poincaré sphere. The PFPS series is bidirectional. Squeezers within the device operate at various fixed frequencies, with the highest speed reaching 700kHz. This device employs advanced digital circuitry to ensure a uniform State of Polarization (SOP) distribution across a wide operational temperature range, rendering it suitable for demanding sensor field applications. This self-contained module operates without requiring manual adjustments or input controls, simplifying its usability. Installation involves straightforward steps: connect the input and output fibers and plug in the included 12V DC power supply. Users should allow approximately 5 minutes for the module to stabilize thermally after activation.
