Abstract

Systems and methods for ferrite redundancy switch networks are disclosed. In one embodiment, a redundant ferrite switch system comprises: a first plurality of circulator modules, a second plurality of circulator modules, and a plurality of components coupled to the first plurality of circulator modules and coupled to the second plurality of circulator modules, wherein the first plurality of circulator modules and the second plurality of circulator modules is able to route a path through the redundant ferrite switch system when more than two components in the plurality of components have failed. The first plurality of circulator modules and the second plurality of circulator modules each comprise, respectively: a plurality of inputs; a plurality of outputs; and a plurality of circulators connecting the plurality of inputs to the plurality of outputs.
