Zusammenfassung:	The present invention relates to a network node configured to operate in an optical fiber network. The network node comprises a QKD communication unit adapted to communicate with another QKD communication unit of at least one other network node of the optical fiber network according to a CV-QKD mode and/or a DV-QKD mode. The present invention also discloses a control unit 5 configured to control the QKD communication unit to operate in at least one of the CV-QKD mode and the DV-QKD mode. The control unit is configured to switch operation of the QKD communication unit between the CV-QKD mode and the DV-QKD mode.
