The recent evolutions in the convergence of QKD and classical communication systems are described, together with the relevance of SDN as a suitable approach for a real integration between QKD and WDM networks. Preliminary experimental results on a discrete-variable QKD prototype working in the O-band co-propagating with 40 50-GHz C-band information channels are reported, showing the capabilities of QKD in short/medium reach optical networks.
