Characterization of Real-Time PMD and Chromatic Dispersion Monitoring in a High-PMD 46-Gb/s Transmission System

We demonstrate performance monitoring based on the electronic compensation provided within a dual-polarization quadrature-phase-shift-keyed coherent receiver. Measurements were made over an 8 times 100-km system with distributed high polarization-mode-dispersion fiber. A laboratory demonstration of in-service monitoring was completed over a ten-day period.
