SK Broadband announced on the 18th that it will begin commercial services for the international undersea cable SJC2 (Southeast-Asia Japan Cable 2), which connects seven countries in Asia, including Korea, Japan, Singapore, and Hong Kong.
SJC2 is an international undersea cable with a total length of 10,500 kilometers, connecting major digital hubs in 10 regions across seven Asian countries, including Busan, Korea. In Korea, SK Broadband participated exclusively.
The latest transmission technology and systems of SJC2 process data much faster and more reliably than existing undersea cables. With a data processing capacity of 9 terabits per second (Tbps), it enables 360,000 subscribers to simultaneously watch UHD quality (25 Mbps) videos, and boasts the speed to download 281 full HD (4GB) movies in one second.
SK Broadband enhanced its basic competitiveness to reliably manage growing internet traffic demands in the AI era by expanding the network infrastructure in the Asia-Pacific region through the opening of SJC2. Additionally, it has laid the foundation for global business expansion in areas such as international dedicated lines, data centers, big data, and cloud services.
Ha Min-yong, head of the AI DC business division at SK Broadband, noted, "With the commercialization of the SJC2 undersea cable, we expect to greatly improve service stability and business scalability to meet various demands in the AI era," and added, "We will continue to do our best to secure future growth engines."
SK Broadband has participated in the SJC2 consortium since 2018 and began commercial services after completing construction in May of this year and undergoing internal testing. Since March of this year, it has also been involved in the consortium for the construction of the international undersea cable E2A (East Asia To North America), which connects Korea, the United States, Japan, and Taiwan.
