The Fiber-Control MPC1-01 Polarization-Controller is a motorized, computer-controlled device that provides precise and dynamic adjustment of polarization states in single-mode optical fibers. It employs a patented all-fiber Lefèvre loop design to achieve stable, rapid SOP control without altering time-averaged power. The continuous fiber path enables high power handling and ultra-low insertion loss, making it ideal for component testing, PDL measurements, PMD applications, and polarization scrambling.
