Abstract
An optical switching system includes a connection information memory portion () that stores connection information between input ports and output ports, a control characteristic memory portion () that stores control characteristic data of micro mirrors with respect to each of a plurality of temperatures, a temperature sensor () that senses a temperature in the optical switching system, and a computing portion () that refers to the control characteristic data stored in the control characteristic memory portion so as to calculate a controlled variable for the angle control of the micro mirrors based on the connection information stored in the connection information memory portion and the temperature sensed by the temperature sensor.
