<p>The present invention relates to a node of an optical network, methods and service edge hub devices (50)attachable to an optical network carrying data traffic comprising data information on a number of optical wavelength channels in one or more optical fibres. Said hub device comprising one or more optical ports (78a-d) connectable to one or more service equipment arrangements (70) for digital processing the received data information, the hub comprising a wavelength switching means (60) configured to connect each channel to the ports (78a-d), wherein the wavelength switching means (60) comprises an optical splitter arrangement (100) for spreading and directing the channels to the different ports (78a-d), in one direction, and network ports (52), in the other direction.</p> |
