ABSTRACT:
A shared directional multichannel for efficiently transmitting k=( log.sub.p n choose (p-1) concurrent, non-interfering transmissions from a set of m.gtoreq.k source stations, each having p transmitters, to a set of n destination stations, each having one receiver, without active repeater components. The multichannel architecture permits implementation of an efficient single-hop multichannel system using optical star couplers in a manner that limits the power spreading loss to the n/p value known for bus-oriented networks instead of n.sup.2 /p. Several coupling stages are employed, each stage having a plurality of identical substantially-square directional couplers, to obtain channel concurrency k, which is an improvement over the concurrency p available in bus-oriented networks, without the higher power spreading loss normally arising from the larger number of connections between each source station and every destination station.
