Sungsang is a town in South Sumatra, Indonesia, situated near the delta of the Musi River where it meets the Bangka Strait. As a coastal settlement at the mouth of one of Sumatra's major river systems, Sungsang serves as a submarine cable landing point within Indonesia's broader national network. Two submarine cables come ashore here, both operating exclusively within Indonesian waters and forming part of the country's domestic connectivity infrastructure.
The two cables landing at Sungsang — the Biznet Nusantara Cable System-1 (BNCS-1) and PASULI — connect Indonesian endpoints to one another, meaning this landing point contributes to intra-national submarine cable links rather than to any international or intercontinental corridor. Together they place Sungsang within the domestic segment of Indonesia's submarine cable map, a country that hosts 70 submarine cables across 139 landing points in total.
Biznet Nusantara Cable System-1 (BNCS-1) is a domestic Indonesian submarine cable with a length of 105 km. It reached ready-for-service (RFS) status in 2024 and connects landing points within Indonesia. As one of the more recently completed cables at this location, BNCS-1 represents the newest addition to Sungsang's submarine cable infrastructure.
PASULI is a shorter domestic submarine cable measuring 40 km in length, with an RFS year of 2019. Like BNCS-1, it connects points within Indonesia, forming part of the intra-island or inter-regional domestic network in the South Sumatra area. Its relatively compact length suggests a more localised routing between nearby Indonesian endpoints.
Within Indonesia's submarine cable landscape, Sungsang ranks in the top 85 percent of the country's 143 landing points by cable count, hosting 2 cables. This places it well behind major hubs such as Batam with 20 cables, Jakarta and Tanjung Pakis each with 9, and Manado with 8, but its role as a domestic landing point in South Sumatra still contributes to the geographic spread of Indonesia's national cable network. Sungsang is among many smaller landing points that collectively extend submarine connectivity across the archipelago beyond the primary gateway cities.
Sungsang functions as a two-cable domestic terminus rather than a multi-cable international hub. Both cables landing here — BNCS-1 and PASULI — operate entirely within Indonesian waters, meaning this landing point serves the national connectivity fabric rather than routing traffic between Indonesia and other countries. The combination of a shorter cable (PASULI at 40 km) and a longer one (BNCS-1 at 105 km) suggests Sungsang connects to at least two distinct Indonesian endpoints across these two systems.
In the broader Indonesian submarine cable graph, Sungsang illustrates how a country with 70 cables distributed across 139 landing points extends submarine infrastructure into smaller coastal towns and delta communities, rather than concentrating all capacity at a handful of major gateways.
