Methods and apparatus are described for an n-Way, Serial-Channel interconnect. An apparatus includes a communications network interconnect including an input layer including a plurality of input channels; a multicast channel branching fabric coupled to the input layer; and a modular output layer coupled to the multicast channel branching fabric layer, the modular output layer including a plurality of individual serial data channels; and a plurality of sets of endpoints, each set of endpoints coupled to one of the plurality of individual serial data channels.
