Advanced Multifunction Polarization Controller— PolaMight-II™ 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.
