詳細(xì)信息

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

◆GPIB IEEE 488.2 & RS-232 and BTM standard

◆Labview 6.0 driver provided. May be used with C,C++, VB, or any other development language featuring GPIB support

◆950 nm to 1070 nm or 1300 nm to 1600 nm

Applications

◆Component level PDL measurements

◆Sub-system PDL testing

◆General purpose in-line control of the SOP

◆Low to medium-speed polarization scrambler

◆Polarization pattern generator

◆Maximize or minimize signal intensity with feedback from optical power meters (or OSA)

◆Component within PMD emulator

◆Component within PMD compensator

◆Polarization stabilizer
