Abstract
A compound optical circuit switches and methods are disclosed. Two or more 1st-tier switches may be coupled to one or more 2nd-tier switches. Each of a plurality of input ports may be connected to a respective input of one of the 1st-tier switches and each of a plurality of output ports may be connected to a respective output of one of the 1st-tier switches. Each connection between an input port and an output port connected to the same 1st-tier switch may be made within the 1st-tier switch. Each connection between an input port and an output port connected to two different 1st-tier switches is made along a respective connection path through the 1st-tier switch connected to the input port, through a selected 2nd-tier switch, and through the 1st-tier switch connect to the output port.
