Nokia and KDDI Corporation have demonstrated quantum-safe optical transport capabilities at KDDI's new Sakai Data Center in Osaka, Japan. The facility is a next-generation site designed to support advanced AI workloads, including real-time training, inference, and data analytics.
The demonstration used Nokia’s 1830 Photonic Service Switch (PSS) with C+L Band and the 1830 Security Management Server (SMS). These components enabled validation of a secure, scalable, and AI-ready infrastructure. Nokia’s optical technologies provided high-capacity transport with data privacy, resiliency, and at-speed quantum-safe encryption across distributed data centers.
The network architecture incorporates built-in cryptography to protect personal data, critical national infrastructure, and sensitive AI workloads during transport.
Ron Johnson, Senior Vice President and General Manager of Optical Networks at Nokia, stated that the initiative addresses demands of modern AI workloads with trusted performance while reducing cybersecurity risks for enterprises, governments, and critical infrastructure providers. He noted the partnership supports KDDI’s quantum-safe and AI-ready data center build-out for secure digital services in Japan and beyond.
Tetsuo Mukai, General Manager of the Access Network Technical Division at KDDI, indicated that high security and performance are required for AI communications infrastructure. He said Nokia’s optical transport solutions fit these needs and contributed to the demonstration’s success. KDDI plans to continue collaboration with Nokia to develop quantum-safe and resilient networks connecting distributed AI data centers across Japan.
