Abstract: Optical network units are connected to at least one optical routing element. The optical network units and the at least one optical routing element are controlled by an optical controller. The two endpoints are controlled by a wireless controller. A communication request between the two endpoints is created by the wireless controller. The communication request is sent from the wireless controller to the optical controller. Further the optical controller identifies the optical network units connected to the two endpoints. The optical controller checks if the optical network units belong to the same optical distribution network and configures the optical network units to transmit and receive a first wavelength spectrum and the at least one optical routing element to route the first wavelength spectrum. The optical controller requests the wireless controller to establish the communication between the two endpoints over the optical distribution network.
