The SJJK submarine cable, also known as the South Japan-Jakarta Cable System, is a high-capacity undersea cable that connects Japan and Indonesia. The cable runs approximately 8,000 kilometers along the Pacific Ocean floor, with landing points in Shima, Japan, and Ancol, Jakarta, Indonesia.
The SJJK submarine cable was completed in 2018 and is owned by a consortium of telecommunications companies, including SoftBank, Facebook, and Telin. The cable has a capacity of 24 terabits per second and is designed to provide reliable, high-speed connectivity between Japan and Indonesia.
The SJJK submarine cable is part of a larger effort to improve internet connectivity in Southeast Asia, which has historically lagged behind other regions in terms of broadband penetration and speed. The cable is expected to provide faster internet speeds, lower latency, and increased reliability for businesses and consumers in both Japan and Indonesia.
Overall, the SJJK submarine cable represents an important investment in the future of global telecommunications infrastructure, and is expected to play a key role in facilitating the growth of digital businesses and economies in Japan and Indonesia.
