The MPC-203 is a High Speed Multifunction Polarization Controller specially designed to meet the high SOP scrambling requirements needed for stress testing coherent receiver’s polarization tracking performance. 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 variable high speed polarization scrambling up to 400,000 revolutions/s. Unlike other high speed polarization scramblers found in the market, this all-fiber, pass-through fiber design comes with the lowest IL, PDL, PMD and activation loss.
