Sakra Island, Singapore: Submarine Cable Landing Point

Sakra Island is a submarine cable landing point located in Singapore, a city-state positioned at the southern tip of the Malay Peninsula and a significant node in the regional submarine cable network. One submarine cable lands at Sakra Island, connecting Singapore directly to Indonesia through a short regional link. This connection reflects the close maritime geography between the two neighboring countries, which are separated by narrow straits and waterways that make submarine cable deployment across this corridor both practical and regionally significant.

The single cable landing at Sakra Island, PGASCOM, establishes a direct bilateral link between Singapore and Indonesia. While Sakra Island hosts fewer cables than several of Singapore's other landing points, it nonetheless forms part of a broader national infrastructure that collectively brings 33 submarine cables ashore across eight landing points in the country.

Cables Landing at Sakra Island, Singapore

PGASCOM is the sole submarine cable landing at Sakra Island. The cable spans 264 kilometers and reached ready-for-service status in 2010. PGASCOM connects Singapore to Indonesia, providing a short-range regional link between these two neighboring nations. The cable's relatively modest length is consistent with the close proximity of Singapore and the Indonesian archipelago, and it serves as a direct point-to-point connection across this narrow maritime corridor.

Regional Context

Among Singapore's eight submarine cable landing points, Sakra Island hosts one cable, placing it alongside Katong as one of the smaller landing points in the country by cable count, while sites such as Tuas (10 cables), Changi North (8 cables), and Changi South (5 cables) accommodate considerably more. Sakra Island ranks within the top 38% of Singapore's landing points by cable count, reflecting its modest but recognized role within the national cable geography.

Network Role

Sakra Island functions as a single-cable terminus, serving the specific bilateral corridor between Singapore and Indonesia via PGASCOM. Rather than operating as a multi-cable hub, it provides a dedicated regional connection across one of Southeast Asia's most active maritime passages. The cable it hosts, at 264 kilometers in length, is substantially shorter than Singapore's average cable length of 10,224 kilometers, underscoring PGASCOM's character as a short-haul regional link rather than a long-distance intercontinental route.

Within the broader Singapore submarine cable graph, Sakra Island represents the country's direct cable-level connection to Indonesia through this particular corridor. Its presence as a distinct landing point—separate from Singapore's larger multi-cable facilities—illustrates how regional short-haul links can occupy dedicated landing infrastructure alongside the longer intercontinental cables that characterize much of Singapore's overall cable portfolio.
