Motorized Polarization Controller, MPC1-02
Controlling polarization is essential within the fiber-optics industry – integrating this function with computer controlled capability enhances measurement speed, accuracy, and overall productivity.
FiberControl’s family of 1, 2 and 4 channel Motorized Polarization Controllers provides stable and rapid control of the state-of polarization of laser sources without altering the time-averaged power. Utilizing the 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 VAC to 264 VAC (47 Hz to 63 Hz). Operating wavelengths: 1070 nm or 1300 nm to 1600 nm.
Features:
◆Single-fiber design
◆Ultra-low insertion loss, PDL, and back-reflection
◆Convenient save/recall settings
◆Multi-rate polarization scrambling
◆AutoScan operation with a wide dynamic range of rotational speed
