Abstract
To provide a self-homodyne detection communication system capable of using a space-division multiplexing signal as a signal for communication. The present invention relates to a space-division multiplexing apparatusincluding a multi-core fiberhaving multiple cores. The space-division multiplexing apparatususes cores other than a corefor self-homodyne detection among the multiple cores included in the multi-core fiberas coresfor communication. The space-division multiplexing apparatus is configured to include a pilot-tone guiding unitand a self-homodyne detection unit
