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
