Non-blocking switch matrix

Abstract:

A N.times.M non-blocking switch matrix, where N and M are integers, includes an input stage having a plurality of m/2-way multiport switches, where quotient m/2 is a positive integer less than M, and an output stage having a plurality of n/2-way multiport switches, where quotient n/2 is a positive integer less than N. The switch matrix further includes a transfer stage having a plurality of transfer switches operatively connected between the input stage and output stage, and selectively applying outputs of the m/2-way multiport switches to inputs of the n/2-way multiport switches such that any given input to the m/2-way multiport switches is connectable to any given output of the n/2-way multiport switches.
