Abstract

400G coherent WDM interfaces were recently standardized by multi-source agreement and standardization forums to enable interoperable operation across DCI, metro/regional and IPoWDM networks of transceivers from various vendors with DSP of different suppliers. The work is under progress for 800G WDM interfaces with the objective to deal with the same use cases at 800G as at 400G. OpenROADM is elaborating for the first time an interoperable probabilistic constellation shaping specification that addresses this need.
