(President: MOROHASHI Hirotsune), Nagoya Institute of Technology (President: Dr. KINOSHITA Takatoshi), and Waseda University (President: TANAKA Aiji, Ph.D.) jointly developed the world's first system for the transparent relay, routing, and switching of high-speed terahertz-wave signals to different locations. Direct conversion of a 32-Gb/s terahertz-wave signal in the 285-GHz band to an optical fiber and its transparent relay and switching to different access points in ultrashort time periods were successfully demonstrated.
