An RS-POTDR prototype device is used in a field trial to investigate the spatial distribution of PMD in deployed fibers in the network of Deutsche Telekom. Results help to identify high-PMD fiber sections which contribute the most to the overall link PMD and need to be replaced to enable 40Gbit/s transmission and beyond.
