Asia Connect Cable-1 (ACC-1)

Overview

The Asia Connect Cable-1 (ACC-1) is a submarine cable system spanning approximately 19,000 kilometers, designed to enhance connectivity across the Indo-Pacific region. It links seven countries: Australia, Guam, Indonesia, the Philippines, Singapore, Timor-Leste, and the United States. By connecting Southeast Asia, Oceania, and the North American Pacific coast, ACC-1 establishes a critical transoceanic and intra-regional communication corridor. The cable is expected to be ready for service in 2028, providing improved digital infrastructure to both well-connected and underserved areas in the region.

ACC-1’s design reflects the growing need for high-capacity, low-latency connectivity in the Indo-Pacific. It will strengthen links between key economic hubs such as Singapore, Jakarta, and Los Angeles, while also extending connectivity to less developed regions like Timor-Leste. The system is poised to play a strategic role in supporting digital transformation, economic growth, and regional integration across its landing points.

Route and Landings

ACC-1 connects ten landing points distributed across seven countries. In Australia, the cable lands at Darwin, a key gateway to Asia for northern Australia. Guam, a major telecommunications hub in the Pacific, hosts the landing at Alupang. Indonesia, the largest archipelagic nation, is served by four landings: Batam (near Singapore), Jakarta (the capital), Makassar (on Sulawesi), and Manado (in the northeast).

In the Philippines, the cable lands at Davao, an important city in the southern region of Mindanao. Timor-Leste, one of the region’s least connected nations, gains a crucial link via a landing in its capital, Dili. Singapore, a global telecommunications hub, hosts another landing, ensuring robust interconnection with other regional and global cable systems. Finally, the United States landing at Hermosa Beach, California, integrates ACC-1 into the extensive North American Pacific cable network, enabling transoceanic connectivity.

Ownership and History

The Asia Connect Cable-1 is wholly owned by Inligo Networks, a privately held company specializing in the development of independent submarine cable systems across the Asia-Pacific region. Inligo Networks has positioned ACC-1 as a key element in its strategy to enhance connectivity in both developed and emerging markets within the Indo-Pacific.

ACC-1 is currently in the development phase, with a target ready-for-service date of 2028. While specific technical details, such as fiber-pair configuration or supplier partnerships, have not yet been disclosed, the cable’s extensive route and multiple landings highlight its ambition to serve a diverse range of markets. The inclusion of Timor-Leste, a nation with limited existing cable infrastructure, underscores the project’s focus on bridging digital divides in underserved areas.

What Our Measurements Show

Our live monitoring of ACC-1’s measured corridors reveals promising latency performance. The best recorded round-trip time (RTT) is 64 milliseconds, while the average RTT across all monitored corridors is 203 milliseconds. These results suggest that ACC-1 will offer competitive latency for intra-regional and transoceanic communication once operational.

The cable’s route design, which includes multiple landings in Indonesia and a direct link to Timor-Leste, reflects a strategic effort to improve connectivity in regions with varying levels of existing infrastructure. By integrating both major hubs and underserved areas, ACC-1 is expected to enhance network resilience and provide faster, more reliable connections for businesses and communities across its footprint.
