摘要：An optical switch according to the present invention includes a multiple-stageoptical-switch unit that includes one input port and a plurality of output ports that areconfigured by connecting multiple stages of optical switching elements each of which

includes three or more optical input-output ports; and a switching control circuit that,when receiving a switching instruction to switch an output destination of light input fromthe input port, executes at first a first control that changes setting of an optical switchingelement that is included in part not overlapping with an optical transmission channelreaching an optical output port before switching in an optical transmission channelreaching an optical output port after switching and is positioned at a point other than abranch point from an overlapping part, and then executes a second control that changessetting of an optical switching element that is positioned at the branch point.
