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.

Abstract: A system to communicate via modulated optical signals of the Li-Fi signal type to transmit data to and from a plurality of defined privileged spaces. The communicating system includes a plurality of first light sources, each first light source emitting, in the infrared, a first modulated optical signal. A plurality of optical fibers, each optical fiber guiding the first modulated optical signal from a single first light source in the direction of an optical interface. The optical interface transmitting the first modulated optical signal into a defined privileged space. Each optical fiber also transporting a second modulated optical signal from the associated defined privileged space in the direction of a device configured to acquire the second modulated optical signal.
