ABSTRACT:
A network interconnection architecture for a plurality of nodes uses sets of grouped node connections which form a plurality of node groups. A central electrically passive interconnection hub is coupled via a signal transmission path to each node group to establish a full mesh coupling between each of the plurality of node groups. An input and output matrix switch along with a pair of 1.times.N multiplexers are also coupled to each of the plurality of node groups and the hub multiplexer via the signal transmission path. The architecture can be further extended to encompass other networks with electrically passive hubs using a sandwich coupling of a matrix switch between two wavelength multiplexers.
