At NTT Network Service Systems Laboratories, we leverage state-of-the-art technology focused on optics with the goal of making the Innovative Optical and Wireless Network (IOWN) concept a reality. We carry out research and development on infrastructure technologies for architecture and network systems that allow for implementation of a network and information processing infrastructure with high-speed, high-capacity communication and vast computing resources that exceed the limits of existing infrastructure, and on communications traffic, quality and operations technologies.
