Zusammenfassung:A plurality of optical sensors (3) are installed in an optical path control device (1) configured to control a plurality of optical paths (2) without using an electrical element. The plurality of optical sensors (3) detect optical signals each passing through at least one of the plurality of optical paths (2). A transmitter (4) simultaneously determines communication states of the plurality of optical paths (2) based on detection of the optical signals by the plurality of optical sensors (3), and transmits information on the determined communication states.
