Controlling polarization is essential within the fiber-optics industry – integrating this function with computercontrolled capability enhances measurement speed, accuracy, and overall productivity.
FiberControl’s Motorized Polarization Controller (MPC-1) provides stable and rapid control of the state-ofpolarization of laser sources without altering the time-averaged power. Utilizing the patented all fiber Lefèvre loop design, this time-tested approach has proven to provide excellent control with ultra-low power variations (PDL). The flexibility inherent within this design allows for a wide range of applications from component testing to PMD related activities. The continuous length of fiber enables high power and ultra-low insertion loss. This design offers a wide range of AutoScan rates and high incremental angular resolution. Supply voltages range from 85 V AC to 264 V AC (47 Hz to 63 Hz).
