✦ AI Summary
KT announced on the 16th the launch of a single 400 Gbps-class international dedicated line between Korea and the U.S., jointly built by KT and the Korea Institute of Science and Technology Information (KISTI).
The circuit is intended to support stable operation of the international research network, and its capacity has been expanded fourfold from the previous 100 Gbps level on the Korea-U.S. route.
KT and KISTI resolved the technical challenge of stable 400 Gbps-class transmission on the ultra-long Korea-U.S. international route, completing submarine cable construction and stability verification to build an environment that connects reliably all the way to Chicago.
KT announced on the 16th that it had launched a single 400 Gbps dedicated international line between Korea and the U.S. The circuit was jointly built by KT and the Korea Institute of Science and Technology Information (KISTI), and is intended to support stable operation of the international research network, it said. The bandwidth of the national science and technology research network on the Korea-U.S. route had previously been around 100 Gbps.
As data-intensive research fields such as AI, mega-science, and astronomy and space science expand, demand for cross-border data exchange has surged. As a result, the company said time delays and bandwidth constraints emerged in the process of transferring ultra-large research data.
Accordingly, KT and KISTI said they jointly resolved the technical challenge of ensuring stable 400 Gbps-class transmission on the ultra-long Korea-U.S. international route. The two sides said they completed the construction of the submarine cable route and verified its stability, building an environment that connects reliably all the way to Chicago. Through this, they said they secured the foundation for operating a superhigh-speed, ultra-large-capacity research network that can be used in actual research settings.
The new circuit has been expanded fourfold to 400 Gbps-class capacity compared with before, improving transmission characteristics for faster speeds and greater stability. This is expected to make ultra-high-speed transfer of large-scale research data possible, while also strengthening the global connectivity of the national research network, expanding support for international joint research, and improving data usability in AI, mega-science, and converged research fields.
KT operates five submarine cable systems: APG, APCN-2, NCP, TPE, and KJCN. These five systems are composed of three in Asia and two in North America, and KT's share of operated capacity accounts for more than half of the submarine cables currently in operation in South Korea.
The target for the expansion of the national science and technology research network circuit is the direct, non-transit NCP submarine cable connecting South Korea and the United States. The expansion minimizes delays and transit risks on international routes, and supports stable operation of the international research network based on international network infrastructure made up of multiple submarine cables and dualized landing stations.
KT has dualized the operation regions of landing stations, the gateway that connects submarine cables and terrestrial communication networks, to Busan and Geoje in South Gyeongsang Province. As a result, even if a network problem occurs on a specific route, international traffic can continue to be processed through alternative paths.
KT plans to continue strengthening its international network competitiveness in response to growing traffic demand from the spread of services in the AI era and increased global data exchange, in addition to expanding the national science and technology research network. To that end, it plans to step up the expansion of submarine cable capacity and the diversification of landing stations in stages. The goal is to expand the foundation for stable global data exchange for domestic and overseas companies and research institutions.
Executive Vice President Jeon Myeong-jun, head of the Enterprise Service Division in KT's Enterprise Business Division, said building the Korea-U.S. 400G national science and technology research network marks an important milestone in enhancing the competitiveness of domestic R&D infrastructure. He added that KT plans to work with KISTI based on its capabilities in operating international submarine cables and global backbones, and that it will continue supporting the strengthening of the global competitiveness of the national research network and digital innovation.
