Jakarta-Bangka-Bintan-Batam-Singapore (B3JS) is an intercontinental submarine cable with a total length of 1031 km. The cable connects Indonesia and Singapore, providing a direct fiber-optic path between these two countries.
The B3JS cable lands in the following cities:
The cable is operated by Moratelindo.
The Jakarta-Bangka-Bintan-Batam-Singapore (B3JS) submarine cable was ready for service in 2012. The status of the cable is unknown, but it has been operational since its launch.
This intercontinental submarine cable connects Indonesia and Singapore, providing a direct fiber-optic path between these two countries. It serves as both a primary data route and a redundancy option for neighboring cable systems in the region, contributing to a mesh of redundant paths that ensure internet traffic remains uninterrupted even when individual systems are damaged or under maintenance.
Indonesia is a major player in Southeast Asia's telecommunications market, with Moratelindo being one of the leading operators.
Singapore is a key hub in Southeast Asia's telecommunications infrastructure, serving as a gateway to the region and beyond. B3JS complements other major cables like SEA-ME-WE 5, which connects Singapore with various points in Southeast Asia and the Middle East.
The corridor served by B3JS is part of a broader network that supports the economic growth and digital transformation of both Indonesia and Singapore. As these countries continue to develop their economies and integrate into global markets, reliable and high-capacity submarine cables like B3JS become increasingly important for supporting data-intensive applications such as cloud services, streaming, and e-commerce.
