A coupler network for coupling N subscriber transmitters to N (=n.multidot.m) subscriber receivers is disclosed. The system exhibits m star couplers each having respectively N transmitter-side input ports for the connection of the N subscriber transmitters and having respectively N receiver-side output ports for connection with respectively N/m subscriber receivers of the N subscriber receivers. In order to reduce the line attenuation of this echo-free coupler network, each subscriber transmitter is connected to a plurality of star coupler input ports and a detector of each star coupler receiver is connected to a plurality of star coupler output ports. A lens system or a fiber taper which make it possible for more light to be coupled in or out (than for individual fibers) is employed for coupling a plurality of star coupler input ports to a subscriber transmitter and/or for coupling a plurality of star coupler output ports to a detector of a subscriber receiver. The specific case N=64, m=4 is illustrated in the drawing.
An optical coupler network having a plurality of nodes with node transmitters and node receivers,
A coupler network according to claim 15, where the optical couplers form a passive data bus system providing interconnection of the node receivers with the node transmitters without requiring optical repeaters, the data bus system being carried on board a mobile vehicle.
An optical coupler network having a plurality of nodes with node transmitters and node receivers, optical star couplers having star coupler input ports connected with said node transmitters and having star coupler output ports connected with said node receivers, for coupling the node transmitters with the node receivers, and
An optical coupler network having a plurality of nodes with node transmitters and node receivers,
