Padang, Indonesia: Submarine Cable Landing Point

Padang is the capital of West Sumatra province and the most populous city on the western coast of Sumatra, Indonesia. As a coastal city, Padang hosts submarine cable infrastructure that connects it to the broader Indonesian archipelago. One submarine cable currently lands at Padang, linking the city directly to another point within Indonesia.

The single cable landing at Padang serves an intra-national, inter-island corridor, reflecting the geographic reality of Indonesia as an archipelagic nation where submarine cables play an important role in connecting dispersed island communities. The Padang-Tua Pejat cable is a relatively short domestic link oriented toward island connectivity within the Indonesian island chain.

Cables Landing at Padang, Indonesia

The Padang-Tua Pejat cable is the sole submarine cable landing at Padang. Spanning approximately 160 kilometres, it reached ready-for-service status in 2019 and is currently listed at draft status. Both endpoints of this cable are located within Indonesia, making it a purely domestic submarine cable connection. Tua Pejat is the administrative capital of the Mentawai Islands regency, situating this cable as a link between the Sumatran mainland and the Mentawai island chain off the western Sumatran coast.

Regional Context

Within Indonesia's extensive submarine cable network — which spans 70 cables across 139 landing points — Padang ranks in the upper 62 percent of all Indonesian landing points by cable count, hosting a single cable. This places it well behind major Indonesian cable hubs such as Batam (20 cables), Jakarta (9 cables), and Tanjung Pakis (9 cables), as well as mid-tier landing points like Manado (8 cables), Dumai (7 cables), and Makassar (6 cables). Padang's profile is therefore that of a specialised, single-purpose domestic landing point rather than a regional aggregation hub.

Network Role

Padang functions as a single-cable terminus, serving a specific and localised connectivity role within the Indonesian domestic submarine cable landscape. The Padang-Tua Pejat cable it anchors is notably shorter than the Indonesian national average cable length of approximately 2,814 kilometres, underscoring its character as a focused inter-island link rather than a long-haul international route. The connection it provides between the Sumatran mainland and the Mentawai Islands addresses the practical challenge of delivering submarine-based connectivity to an offshore island group.

Within the broader Indonesian submarine cable graph, Padang represents one of many specialised landing points that collectively extend network reach to island communities that would otherwise lack direct terrestrial connectivity, complementing the large international-facing hubs that dominate Indonesia's cable landscape.
