KT and KISTI open 400G Korea-US national science research network

KT and KISTI opened Korea's first dedicated 400 Gbps international link between Daejeon and Chicago. Capacity on this route of the national science and technology network quadrupled from 100 to 400 Gbps, needed for large data transfers in AI and astronomy.

• Capacity rose from 100 to 400 Gbps — a 4x increase
• Link connects Daejeon directly to Chicago without intermediate nodes
• Uses the NCP submarine cable; KT operates 5 of more than 10 systems in the country
• Landing stations in Busan and Geoje provide a backup route
