Nongsa: A Gateway Between Indonesia and Singapore
Nongsa, located on the northeastern tip of
Batam Island in Indonesia, is home to two submarine cable landings that play distinct roles in regional connectivity. While Nongsa may not boast the cable density of its neighbor Batam, which hosts an impressive 20 cables, its strategic position and unique connections make it an interesting case in Indonesia's vast submarine cable network.
Two Cables, Two Stories
The first cable landing here is the
Barat Timur Indonesia-1 (BTI-1), a domestic cable stretching 4,500 km and set to be ready for service in 2028. This cable stitches together six landing points across Indonesia, including Balikpapan, Gresik, Makassar, Manado, and Tanjung Pakis. BTI-1 is part of a broader effort to enhance domestic connectivity across the archipelago, linking major urban centers and industrial hubs. Nongsa’s role in this chain is as a connecting node, ensuring Batam Island is integrated into the national network.
The second cable,
Nongsa-Changi, is far shorter at just 50 km but serves a completely different purpose. Set to be operational in 2026, this cable directly links Nongsa to
Changi in Singapore, providing international connectivity. Singapore, a global financial and technological hub, is a critical partner for Indonesia in terms of data exchange and economic collaboration. Nongsa-Changi’s direct route ensures low latency for traffic between the two countries, making it an efficient bridge for cross-border communication.
Latency and Performance
GeoCables’ own latency measurements from Nongsa highlight its performance as a landing point. Across 47 completed checks from nine source cities, the average round-trip latency is 74 ms, with the best observed latency a remarkable 7 ms. This low latency is particularly significant for the Nongsa-Changi cable, which facilitates fast data transfer between Indonesia and Singapore. For businesses relying on real-time communication or data-heavy applications, this speed can make a tangible difference.
Positioning Nongsa in Indonesia’s Cable Landscape
Indonesia is home to 70 submarine cables landing at 139 points, making it one of the most interconnected nations in Southeast Asia. However, not all landing points are created equal. Nongsa’s two cables place it in the top 85% of landing points by cable count, but it pales in comparison to regional peers like Batam (20 cables) or Jakarta (10 cables). Despite this, Nongsa’s role is specialized rather than expansive. Its domestic link via BTI-1 and its international connection via Nongsa-Changi ensure it serves both local and cross-border needs.
Nongsa’s Unique Role
While Batam Island is often associated with industrial activity and dense cable infrastructure, Nongsa stands out as a quieter yet strategically important landing point. Its domestic connection through BTI-1 supports Indonesia’s internal data flow, while its international link to Singapore provides a direct pathway for global connectivity. Together, these cables ensure Nongsa plays a dual role in the region’s digital landscape, balancing local integration with international outreach.
