Product Description:
This PMD Emulation Platform (PMDE) simulates the true nature of PMD. Using 3 of General Photonics’ patented polarization controllers and 3 differential group delay (DGD) lines, the PMDE-301 generates an accurate Maxwellian Probability Density Function with a tunable mean DGD value. The dynamic PMD emulation platform has broad applications in PMD effects evaluation and in calibration of PMD testing setups. Also, it can be used in performance testing of other PMD compensators. The PMDE provides a large, tunable range of DGD values, with very high repeatability and temperature stability. Its 2nd -order PMD value is 70% matched with that of real fiber ( ~ 95% when two PMDE-301s are cascaded). With its easily reconfigurable mainframe and control interface, the PMDE can perform advanced PMD emulation techniques, including importance sampling, multicanonical sampling, etc., with much higher efficiency than other systems currently on the market. The “all-in-one” platform provides most of the desired features for PMD emulation/compensation systems, including first-order and all-order PMD emulation, DGD generation, polarization control and scrambling, cascading feasibility, slow PMD dynamics, etc.
