Ujung Pankah, Indonesia

Ujung Pankah: Submarine Cable Landing Point

Ujung Pankah is a submarine cable landing point located in Indonesia, a nation whose extensive archipelago geography has made submarine cable infrastructure a fundamental part of its telecommunications network. As one of 97 cable landing points spread across Indonesia, Ujung Pankah serves as a terminus for domestic submarine cable connectivity. A single submarine cable lands at this location, connecting it to other points within Indonesia and contributing to the intra-national network that binds together the country's many islands.

The cable landing at Ujung Pankah operates within an exclusively domestic corridor, linking Indonesian locations to one another rather than reaching outward to international destinations. This places Ujung Pankah among the subset of Indonesian landing points dedicated to inter-island connectivity, a role that reflects the practical realities of maintaining communications across one of the world's most geographically dispersed nations.

Cables Landing at Ujung Pankah

SJJK is the sole submarine cable landing at Ujung Pankah. With a total length of 543 kilometres, this cable reached ready-for-service status in 2008, currently carrying a draft status designation. The SJJK cable connects locations entirely within Indonesia, making it a domestically oriented system designed to serve inter-island communication needs rather than international traffic. Its relatively compact length of 543 kilometres is consistent with a cable designed to bridge specific island or coastal segments within the Indonesian archipelago.

Regional Context

Within Indonesia's 97 submarine cable landing points, Ujung Pankah ranks in the top 64 percent by cable count, hosting a single cable. Major Indonesian hubs such as Batam, with 15 cables, and Jakarta and Tanjung Pakis, each with 7 cables, represent far higher concentrations of submarine cable infrastructure. Compared to mid-tier landing points such as Anyer and Dumai, which each host three cables, Ujung Pankah serves a more focused and specialised connectivity role.

Network Role

Ujung Pankah functions as a single-cable terminus within Indonesia's domestic submarine cable graph. The SJJK cable anchors this landing point to intra-Indonesian connectivity, supporting the inter-island links that collectively knit together the national network. Rather than serving as a gateway to international routes, Ujung Pankah's role is defined by its contribution to domestic digital cohesion across the archipelago.

Within Indonesia's broader landscape of 40 submarine cables across 97 landing points, single-cable landing points such as Ujung Pankah form the distributed edges of a network that depends on many localised connections to function as a coherent whole. The presence of this landing point reflects the scale of infrastructure required to connect a geographically complex nation through submarine cable technology.
