Taliabu, Indonesia: Submarine Cable Landing Point

Taliabu is an island located in the North Maluku province of Indonesia, forming the westernmost part of the Sula Archipelago. As an island territory, submarine cable connectivity represents a significant mode of telecommunications linkage to the broader Indonesian national network. One submarine cable lands at Taliabu: the Palapa Ring Middle, a domestic Indonesian system that connects multiple island and coastal communities across the archipelago.

The Palapa Ring Middle cable is an entirely intra-Indonesian system, meaning the connectivity it enables is regional and inter-island in character rather than intercontinental. For an island regency such as Taliabu — which was only separated into its own administrative regency in December 2012 and had a population of 58,047 at the 2020 Census — a direct landing on a national submarine cable system represents a meaningful extension of the country's domestic digital network into its eastern island territories.

Cables Landing at Taliabu

Palapa Ring Middle is a submarine cable system with a total length of approximately 2,100 km, reaching ready-for-service (RFS) status in 2018. The cable is an entirely domestic Indonesian system, with all of its landing points located within Indonesia. It forms part of the broader Palapa Ring initiative, which was designed to extend submarine cable infrastructure to underserved and remote island communities across the Indonesian archipelago. Taliabu is one of the endpoints on this system, connecting the island into the national network alongside other Indonesian landing points served by the cable.

Regional Context

Within Indonesia's submarine cable landscape, Taliabu is a single-cable landing point, standing in contrast to major hubs such as Batam, which hosts 15 cables, and Jakarta and Tanjung Pakis, each serving 7 cables. Manado in North Sulawesi serves 5 cables, while Anyer and Dumai each host 3. Taliabu's role is more narrowly defined, reflecting its status as a remote island regency in eastern Indonesia rather than a gateway hub on major international routes.

Network Role

Taliabu functions as a single-cable terminus within the Indonesian domestic submarine cable network. Its connection via the Palapa Ring Middle system links the island into a broader intra-archipelago corridor, enabling telecommunications continuity between Taliabu and other Indonesian communities served by that cable. The landing point does not currently serve any international cable routes, placing it firmly in the category of a domestic endpoint rather than a multi-cable hub.

Within the regional submarine cable graph, Taliabu's position illustrates how Indonesia's Palapa Ring program extended structured cable connectivity to geographically isolated island regencies that would otherwise depend on satellite or indirect terrestrial links. As a terminus on a nationally planned system, the Taliabu landing point reflects the deliberate reach of Indonesia's domestic submarine cable policy into the North Maluku island chain.
