MPC-202 Multifunction Polarization Controller

The MPC-202 is a multifunction polarization controller with higher speed scrambling and polarization transition functions designed for stress testing of coherent receiver systems.

The MPC-202 is a multifunction polarization controller specially designed to meet the requirements of coherent receiver performance tests. It combines fiber squeezer polarization controllers with proprietary polarization control algorithms to achieve a wide range of polarization control functions.

The MPC-202 has polarization scrambling and square wave transition functions with a slew rate of up to 360 krad/s for polarization tracking speed and recovery time tests.

The MPC-202 also has manual polarization control, modulation, and other scrambling functions similar to the MPC-201.
