Abstract:
1. A full-duplex, deterministic, and redundant frame switching network comprising at least one frame switch to which are connected a plurality of equipment, at least one terminal being a subscriber to said network, and a passive optical network connected between the frame switch and the plurality of equipment, the optical line terminal of which consists of the frame switch and the optical network terminals of which consist of said equipment, said passive optical network broadcasting over the downlink every frame output by said frame switch to all said equipment and multiplexing over the uplink the frames transmitted by said equipment; wherein the passive optical network comprises an optical coupler connected to a port of said frame switch by a first optical fiber and to said plurality of equipment by a plurality of second optical fibers; and wherein, for a virtual link output by a first equipment and intended to a second equipment of said plurality, the first and second equipment being connected to the optical coupler, said virtual link being incident on said port of the frame switch, said switch is configured to selectively loop this virtual link back to said port.
