Penarik, Indonesia: Submarine Cable Landing Point

Penarik is a submarine cable landing point located in Indonesia, a nation whose coastlines host an extensive network of undersea cable infrastructure spanning 70 cables across 139 landing points. As a landing point, Penarik connects Indonesian territory to the regional submarine cable grid. One submarine cable lands at Penarik, linking it to the broader connectivity framework shared across Indonesia and neighboring Malaysia.

The single cable serving Penarik, the East-West Submarine Cable System, operates as a regional link between Indonesia and Malaysia, enabling cross-border data and telecommunications exchange across the maritime corridor that separates the two countries. While Penarik hosts fewer cables than Indonesia's largest hubs, its participation in this bilateral connection places it within an active regional submarine cable environment.

Cables Landing at Penarik

The East-West Submarine Cable System is the sole submarine cable landing at Penarik. Spanning approximately 950 kilometers, the cable reached ready-for-service status in 2004, making it one of the earlier submarine cable deployments in the Indonesian network, where the first cable nationally entered service in 2003. The system connects landing points in Indonesia and Malaysia, forming a direct submarine link between the two neighboring countries across the regional sea corridor.

Regional Context

Within Indonesia's submarine cable landscape, Penarik is a single-cable landing point, placing it alongside the less cable-dense end of Indonesia's 139 landing points. Major Indonesian hubs such as Batam (20 cables), Jakarta (9 cables), Tanjung Pakis (9 cables), Manado (8 cables), Dumai (7 cables), and Makassar (6 cables) host considerably more cable infrastructure, reflecting the concentration of connectivity in Indonesia's largest commercial and strategic centers. Penarik ranks in the top 62 percent of Indonesian landing points by cable count, indicating that a significant number of the country's landing points host no more cables than Penarik does.

Network Role

Penarik functions as a single-cable terminus rather than a multi-cable hub, serving as the Indonesian anchor for the East-West Submarine Cable System's bilateral route between Indonesia and Malaysia. This landing point enables a direct submarine pathway between the two countries, contributing to the regional connectivity fabric that links the Indonesian archipelago with peninsular Southeast Asia.

Within the broader Indonesian submarine cable graph, Penarik represents one of many distributed landing points that collectively extend national and regional connectivity beyond the major urban hubs, ensuring that Indonesia's cable network reaches beyond its most densely served locations.
