MPC-202 – Advanced Multifunction Polarization Controller

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 triangle-wave 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.

A video demonstration can be watched from the Gallery (below).
