The Jakarta-Bangka-Bintan-Batam-Singapore (B3JS) submarine cable is a high-speed, fiber-optic cable system that connects Jakarta, Indonesia to Singapore via the islands of Bangka, Bintan, and Batam. The cable spans approximately 1,200 kilometers, with a design capacity of 3.84 Terabits per second (Tbps).
The B3JS submarine cable was constructed by a consortium of telecommunications companies including PT Telekomunikasi Indonesia (Telkom), Singapore Telecommunications Limited (Singtel), and PT Mora Telematika Indonesia (Moratelindo). The cable system is owned and operated by Telkom.
The B3JS submarine cable system was officially launched in August 2017 and has since become an essential component of Indonesia's telecommunications infrastructure, providing high-speed connectivity between the country's capital city and Singapore, one of the world's most important business and financial centers.
The B3JS cable system features advanced technology, including dense wavelength division multiplexing (DWDM) and optical amplifiers, which enable it to provide high-speed, low-latency connectivity that is essential for a range of applications, including e-commerce, online gaming, and cloud computing.
Overall, the B3JS submarine cable has played a critical role in improving Indonesia's connectivity to the rest of the world, enabling the country to benefit from the transformative power of digital technologies and helping to promote economic growth and development.
