A super non-blocking switch matrix has the most flexible architecture, yet most complex when compared to blocking and non-blocking types. In this configuration any input can be switched to any and all outputs. In addition to this, multiple inputs can be routed to the same output. Input 1, for example, can be simultaneously switched to every output or selectively switched to several outputs at once. Input 2 can also be simultaneously switched to every output or selectively switched to several outputs at once, regardless of how Input 1 (or any other input) is routed. The same is true for all of the remaining inputs.
This architecture is accomplished by a 1 x N splitter at each input, an N x 1 splitter at each output and single-pole single-throw interconnects between all the splitter ports.
The super non-blocking switch matrix suffers from the same isolation issues as the non-blocking matrix due to the use of splitters and the dependence upon splitter isolation characteristics. Insertion loss is worse than the non-blocking configuration insertion loss because there are twice as many splitters. Insertion loss can be improved by adding amplifiers to make up for any internal losses.
