Abstract: An optical backplane for an optical communication network architecture distributing data to equipment. An optical demultiplexer having an input port and at least two output ports. The input port coupled to an optical fiber to carry at least two multiplexed channels of different wavelengths, a control/management channel to control/manage the network and a service dedicated channel. The output ports deliver the control/management channel and at least one service dedicated channel. A coupler receives and transmits one portion of the control/management channel to an interface box coupled to an item of equipment, and another portion of said channel to an optical multiplexer. A routing device for each output port receives a channel either to transmit said channel to the optical multiplexer in a first position or to transmit one portion of said channel to the interface box and another portion of said channel to the optical multiplexer in a second position.
