Abstract
Compound optical circuit switches and methods are disclosed. Two or more 1-tier switches may be configured to make selectable optical connections between a plurality of 1-tier inputs and a plurality of 1-tier outputs. Each 1-tier switch may include input and output power meters to measure optical powers of signals received at the 1-tier inputs and optical powers of signals output from the 1-tier outputs, respectively. At least one 2-tier switch may include plural 2-tier inputs optically connected to respective 1-tier outputs, plural 2-tier outputs optically connected to respective 1-tier inputs, and plural 2-tier rotatable mirror elements to make selectable optical connections from the 2-tier inputs to the 2-tier outputs. A 2-tier switch controller may control positions of at least some of the 2nd-tier mirror elements based on optical power measurement data from the input power meters and the output power meters of the 1-tier switches.
