Quantum communications in reconfigurable optical networks: DWDM QKD through a ROADM

We demonstrate coexistence of classical and quantum signals for quantum key distribution in a DWDM reconfigurable networking environment using a ROADM. We show how the limiting noise mechanism can depend on the link configuration.
