Polarization Optimized PMD Source – PMDPro™
PMDPro™ is a breakthrough PMD source that can deterministically generate precise 1st order PMD up to 180 ps and 2nd order PMD up to 8100 ps2. Its quasi-continuous operation mode enables independent generation of first order and wavelength independent second order PMD for uniform coverage of the PMD space. It contains an automatic polarization controller and two polarimeters that monitor the state of polarization (SOP) and degree of polarization (DOP) before and after the PMD generating elements. The polarization controller can be used with the front polarimeter to automatically align and maintain the input SOP at 45° from the principal axis of the DGD element to obtain the worst-case first order PMD effect. Alternatively, the controller can automatically adjust and maintain the input SOP using the feedback from the rear polarimeter to either minimize or maximize the output DOP for each PMD setting. Minimizing the output DOP enables testing of the worst-case total PMD effect, while maximizing the DOP turns the PMDPro™ into a PMD compensator, allowing the user to obtain optimized PMD values for PMD compensation. PMDPro™ can also perform PMD emulation by generating statistical PMD distributions. Finally, the polarization controller and polarimeters enable variable rate scrambling and deterministic polarization control functions, including trace generation and polarization stabilization at any SOP. PMDPro™ makes your PMD related systems testing simple, fast, and professional.
