The MPC-203 is a High Speed Multifunction Polarization Controller specially designed to meet the high SOP scrambling requirements needed for stress testing a 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 high speed polarization scrambling with a maximum SOP change rate of up to 11 Mrad/s. Unlike other high speed polarization scramblers found in the market, this all-fiber, pass-through design ensures low IL, PDL, PMD and activation loss.
