Raha, Indonesia: Submarine Cable Landing Point

Raha is the main town and port on Muna Island, located in Southeast Sulawesi, Indonesia, where it serves as the capital of Muna Regency. As a coastal settlement on an island, Raha is connected to Indonesia's national submarine cable network through undersea infrastructure reaching its shores. One submarine cable lands at Raha, linking the town to the broader domestic telecommunications grid of the Indonesian archipelago.

The single cable serving Raha is the Palapa Ring Middle, an entirely domestic system connecting points within Indonesia. This system reflects the broader national effort to extend fiber-optic submarine connectivity across Indonesia's many islands, ensuring that island communities such as Raha on Muna Island are integrated into the country's internal communications network rather than relying solely on satellite or terrestrial alternatives.

Cables Landing at Raha

The Palapa Ring Middle is the sole submarine cable landing at Raha. The system has a total length of 2,100 kilometres and reached ready-for-service status in 2018. All endpoints on the Palapa Ring Middle are located within Indonesia, making it a purely domestic cable designed to interconnect Indonesian islands and communities. Raha represents one node along this intra-national system, which spans a considerable distance across the central section of the Indonesian archipelago.

Regional Context

Within Indonesia's submarine cable landscape, Raha is a single-cable landing point, standing apart from major hubs such as Batam, which hosts fifteen cables, or Jakarta and Tanjung Pakis, each with seven. Even compared to mid-tier landing points such as Manado with five cables or Anyer and Dumai each with three, Raha serves a more limited connectivity role. Its position reflects the reality that domestic ring systems like Palapa Ring Middle extend connectivity to smaller island communities that would not otherwise feature in large international cable routes.

Network Role

Raha functions as a domestic terminus within the Palapa Ring Middle system, enabling intra-Indonesian connectivity for Muna Island and the surrounding Southeast Sulawesi region. As a single-cable landing point, it does not operate as a multi-cable hub, but rather as an endpoint that brings national fiber-optic infrastructure to a community that would otherwise be outside the reach of submarine cable connectivity. The cable's 2018 RFS date marks the point at which Raha became integrated into Indonesia's domestic submarine cable grid.

In the broader regional submarine cable graph, Raha's significance lies in its role as evidence of Indonesia's domestic cable expansion strategy, which aims to connect outlying island towns to the same national network that serves far larger cities.
