Madura, Indonesia: Submarine Cable Landing Point

Madura is an Indonesian island located off the northeastern coast of Java, separated from the main island by the narrow Madura Strait, and forming part of the province of East Java. As a landing point in Indonesia's submarine cable network, Madura hosts one submarine cable, connecting it to the broader regional and international digital infrastructure. That cable, the Indonesia Global Gateway (IGG) System, links Madura with Singapore and other points within Indonesia, establishing a corridor that spans both intra-archipelago and intercontinental routes.

Indonesia's submarine cable network is extensive, with 70 cables landing across 139 landing points nationwide. Within that landscape, Madura represents a single-cable landing point, ranking within the top 62 percent of Indonesian landing points by cable count. Its position on the island of Madura gives it a distinct geographic role along the Java Sea corridor, where submarine cable routes frequently thread between Indonesia's major islands and outward toward Singapore and beyond.

Cables Landing at Madura

The Indonesia Global Gateway (IGG) System is the sole submarine cable landing at Madura. Stretching approximately 5,300 kilometres, the cable reached ready-for-service (RFS) status in 2018, though its status is noted as draft. The IGG System connects landing points in Indonesia and Singapore, making it a cable that serves both domestic Indonesian connectivity and a direct link to one of Southeast Asia's principal telecommunications hubs. The cable's length and geographic reach position it as a significant regional system operating across the western portion of the Indo-Pacific maritime corridor.

Regional Context

Among Indonesian landing points, Madura hosts a single cable compared to major hubs such as Batam with 20 cables, Jakarta with 9, and Tanjung Pakis also with 9. Manado, Dumai, and Makassar each host between 6 and 8 cables, placing them considerably ahead of Madura in terms of cable density. Madura's single-cable profile is characteristic of a secondary landing point within Indonesia's broader and highly distributed submarine cable geography.

Network Role

Madura functions as a single-cable terminus within Indonesia's submarine cable network, providing a direct connection via the Indonesia Global Gateway (IGG) System to Singapore and to other Indonesian landing points on the same cable. This positions Madura as a node on an intra-ASEAN corridor, contributing to the mesh of routes that links Indonesia's many islands with the regional internet exchange environment centred in Singapore.

While Madura does not operate as a multi-cable hub, its participation in the IGG System means the island is integrated into a 5,300-kilometre regional network. In the broader Indonesian submarine cable graph, where connectivity is distributed across 139 landing points of varying scale, single-cable termini such as Madura contribute to the geographic spread of network access across the archipelago's diverse island territories.
