Abstract: A radio-frequency data transport infrastructure for transmitting radio-frequency data to and from equipment via optical fibers. Such data transport infrastructure being particularly suitable for equipping an aircraft.

Abstract: An optical emitter-receiver module includes a light source, a photodetector and a fiber. The light source emits an emitted beam. The fiber includes a core and an optical axis. The fiber has an outer surface, inclined at an angle of 45° with respect to the optical axis, having a mirror. The fiber has a notch, extending to the core of the fiber and having a face having a dichroic filter for reflecting a received beam. The light source is arranged relative to the mirror so that the emitted beam is reflected by the mirror and transmitted in the fiber. The photodetector and the face of the notch are positioned so that the received beam reflected by the dichroic filter is directed towards the photodetector.

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.
