Pringgabaya: Submarine Cable Landing Point

Pringgabaya is a submarine cable landing point located in Indonesia, a nation whose archipelagic geography makes underwater cable infrastructure a primary means of telecommunications connectivity across its islands. As a coastal landing point, Pringgabaya serves as a terminus for domestic submarine cable infrastructure linking different parts of the Indonesian archipelago. One submarine cable lands at Pringgabaya, connecting it to other locations within Indonesia and supporting inter-island data transmission corridors.

The single cable landing here, the Mataram Kupang Cable System, operates entirely within Indonesian waters, reflecting the scale of domestic submarine cable investment required to connect Indonesia's dispersed island groups. With Indonesia hosting 40 submarine cables across 97 landing points, Pringgabaya represents a more modest node within a broad national network, yet its participation in an intra-Indonesia route underlines the role that smaller landing points play in completing regional connectivity across the country.

Cables Landing at Pringgabaya

The Mataram Kupang Cable System (MKCS) is the sole submarine cable landing at Pringgabaya. Stretching 1,318 kilometres, this cable reached its ready-for-service status in 2011, initially on a draft basis. The MKCS connects locations within Indonesia, making it an entirely domestic cable system. Its endpoints are all situated within Indonesian territory, meaning the cable serves the function of linking Indonesian islands across what can be considerable maritime distances, rather than providing international connectivity to foreign nations.

Regional Context

Within Indonesia's submarine cable landscape, Pringgabaya ranks in the top 64 percent of the country's 97 landing points by cable count. Compared to major Indonesian hubs such as Batam, which serves 15 cables, Jakarta with 7, and Tanjung Pakis also with 7, Pringgabaya hosts a single cable and represents a more specialised, single-route node. Its regional peers span a wide range of connectivity scales, from highly interconnected international gateways to smaller domestic waypoints similar to Pringgabaya itself.

Network Role

Pringgabaya functions as a single-cable terminus within the Indonesian domestic submarine cable network. Through the Mataram Kupang Cable System, it participates in an intra-Indonesia corridor spanning 1,318 kilometres, enabling inter-island connectivity between Indonesian locations served along that route. It does not currently serve as a multi-cable hub or as a point of international connectivity, distinguishing it functionally from larger Indonesian landing points that handle intercontinental or regional cross-border traffic.

In the broader Indonesian submarine cable graph, landing points such as Pringgabaya demonstrate that nationwide connectivity across an archipelago of this scale depends not only on major international hubs but also on a distributed network of smaller domestic nodes, each contributing to the overall reach of the country's underwater cable infrastructure.
