Abstract
An interconnect element incorporates a plurality of smaller, substantially identical, interconnect modules. Multiple identical elements can in turn be combined to form larger interconnect networks. Signal paths in the elements can be implemented with optical fibers or electrical conductors.
Claims19
A method of implementing an interconnect fabric for a communications switch that has inputs and outputs, the method comprising;
- selecting N a number of switch inputs;
- selecting K a second number, less than the number N of switch inputs;
- providing a plurality of K×K substantially identical interconnect modules, each module includes K2 separate bidirectional, optical communications paths, each path has one signal input and one signal output;
- and
- coupling the switch inputs to the plurality of modules with only one switch input per path
