Software-Defined WDM Optical Transport in Disaggregated Open Optical Networks

Transparent optical networks operated by WDM coherent optical technologies for data transport are moving-on towards the implementation of the openness paradigm. In such a context, disaggregated network elements and subsystems can be abstracted to manage and control propagation of WDM optical data transport. It enables the application of the software-defined paradigm down to the physical layer, with optical transport fully summarized by a quality of transmission estimator.
