We report the first successful coherent 100G IP over WDM alien wavelength field trial over WDM infrastructures spanning a total distance of 769 km, demonstrating the feasibility and robust performance of a simplified 100G IP over WDM core network architecture. Key performance aspects have been investigated including co-propagation of a 100G IP over WDM alien wavelength and native wavelengths generated from WDM transponders, polarization mode dispersion tolerance, and operation without in-line dispersion compensation modules. We also demonstrated the feasibility of a 100G IP over WDM alien wavelength over multiple WDM systems and optical router or regenerator bypass. In addition, we show evaluation results on the key performance management and monitoring functions with a coherent 100G IP over WDM optical interface in the core router.
