Advanced Multifunction Polarization Controller—
PolaMight-II™

MPC-202

The MPC-202 is an advanced Multifunction Polarization
Controller specially designed to meet the requirements of
coherent receiver performance tests. It combines General
Photonics’ award winning PolaRite™ II/III polarization
controller with proprietary polarization control algorithms to
achieve a wide range of polarization control functionalities,
including high speed quasi-uniform rate polarization
scrambling, random-rate polarization scrambling with
Rayleigh rate distribution, discrete-state polarization
scrambling with high slew rate, sine, square, and trianglewave SOP modulation, and manual polarization control functions. In particular, the “Tornado” quasi-uniform
rate polarization scrambling function can achieve a high SOP scrambling rate of up to 60,000 revolutions/s
(more than 360 krad/s) with a narrow rate distribution clustered around the highest rate. In short, the MPC202 is an ideal tool for production or laboratory testing of polarization related functions and parameters,
including passive/active component characterization, performance tests of fiber optic interferometers, sensor
systems, RF photonics systems, etc. The quasi-uniform rate high speed scrambling function is particularly
useful for SOP tracking speed testing of coherent receivers. The square wave SOP modulation and the
discrete SOP scrambling functions are ideal for SOP recovery time tests.
