Terempa: Submarine Cable Landing Point

Terempa is a landing point located in Indonesia, serving as a node in the country's submarine cable network. Two submarine cables land at Terempa: the Palapa Ring West and the East-West Submarine Cable System. Together, these cables connect Terempa into both domestic Indonesian connectivity and a cross-border corridor linking Indonesia with Malaysia.

The Palapa Ring West operates as a domestic Indonesian cable, providing intra-archipelago connectivity, while the East-West Submarine Cable System extends the network internationally toward Malaysia. This combination positions Terempa as a point where regional inter-island links and international connections converge, serving a corridor that spans both within the Indonesian archipelago and across the maritime boundary to Malaysia.

Cables Landing at Terempa

Palapa Ring West is a submarine cable with a length of 1,980 km, which reached ready-for-service status in 2018. The cable connects landing points across Indonesia, operating entirely within Indonesian territory. It forms part of the broader Palapa Ring initiative designed to extend domestic submarine cable infrastructure across the Indonesian archipelago.

East-West Submarine Cable System is a submarine cable measuring 950 km in length, which reached ready-for-service status in 2004. The cable connects landing points in Indonesia and Malaysia, establishing a bilateral submarine link between the two neighboring countries. As one of the earlier cables in the region, it has provided international connectivity between Indonesia and Malaysia for over two decades.

Regional Context

Within Indonesia's submarine cable landscape of 70 cables across 139 landing points, Terempa ranks in the top 85% of landing points by cable count with its two cables. Major Indonesian hubs such as Batam, which hosts 20 cables, and Jakarta, which hosts 9, handle substantially greater cable volumes. Terempa serves a more focused role compared to these larger nodes, contributing nonetheless to the density and geographic distribution of Indonesia's overall submarine cable network.

Network Role

Terempa functions as a two-cable landing point, connecting it to both the domestic Indonesian cable tier through Palapa Ring West and the international tier through the East-West Submarine Cable System's link to Malaysia. Rather than a large multi-cable hub, it represents a targeted node that combines intra-archipelago and bilateral international connectivity in a single location.

The presence of both a domestic and an international cable at Terempa means that the landing point participates in two distinct connectivity corridors simultaneously. Within the broader Indonesian submarine cable graph, landing points like Terempa that carry cables of different geographic scopes contribute to the distributed character of the country's submarine network across its many islands and maritime zones.
