Asia Connect Cable-1 (ACC-1): Planned Trans-Pacific Connectivity

The Asia Connect Cable-1 (ACC-1) is a planned submarine cable system that aims to connect key locations across the Asia-Pacific region and the United States. With a total length of approximately 19,000 kilometers, it is designed to link ten landing points spanning Guam, Indonesia, Australia, the Philippines, Timor-Leste, Singapore, and the United States. Owned by Inligo Networks, the cable is expected to be ready for service (RFS) in 2028, though it is not yet operational as of now. What makes ACC-1 particularly interesting is its ambitious scope, traversing multiple countries and regions with diverse economic and technological profiles. However, details about its design capacity, fiber pairs, supplier, and technology have not been publicly disclosed, leaving some aspects of its technical implementation uncertain. Its eventual role in the global telecommunications landscape will depend on how effectively it integrates with existing systems and addresses redundancy needs.

Route

The ACC-1 cable is planned to connect ten landing points across the Asia-Pacific region and the United States, forming a trans-Pacific corridor. The landing points include Alupang in Guam, Batam, Jakarta, Makassar, and Manado in Indonesia, Darwin in Australia, Davao in the Philippines, Dili in Timor-Leste, Singapore, and Hermosa Beach in the United States. This route is strategically significant, as it links major economic hubs such as Singapore and Jakarta with emerging markets like Timor-Leste and Davao, while also providing direct connectivity to the United States.

Why it was built and what it carries

ACC-1 is being developed to address the growing demand for high-capacity, low-latency connectivity between Asia and the United States. The cable's planned route reflects its role in supporting data-intensive industries, cloud services, and digital transformation across the region. While its design capacity has not been disclosed, the cable is expected to contribute significantly to the bandwidth available in the Asia-Pacific corridor. Additionally, the cable will likely enhance connectivity for underserved regions such as Timor-Leste, which currently has limited international submarine cable infrastructure. By integrating these regions into the global network, ACC-1 could facilitate economic growth and digital inclusion.

History: what can be established

The GeoCables database records ACC-1's ready-for-service year as 2028. As of now, there are no conflicting industry sources suggesting a different timeline, though delays in submarine cable projects are not uncommon due to factors such as permitting, environmental assessments, and geopolitical considerations. Publicly available information about the cable's development timeline is limited, making it difficult to assess its current progress.

Capacity and technology

Details about ACC-1's design capacity, fiber pairs, supplier, and technology have not been disclosed in public sources. Without operator documentation, it cannot be stated whether the cable will employ advanced technologies such as space-division multiplexing (SDM) or feature high fiber pair counts. These elements will ultimately determine the cable's performance and scalability.

Latency: the physics

The theoretical one-way light propagation latency for ACC-1 over its 19,000 km wet segment is approximately 93.1 milliseconds, with a round-trip time (RTT) floor of 186.3 milliseconds. However, real-world latency will be higher due to additional factors such as terrestrial network delays, signal processing at terminals, and routing inefficiencies. Live latency measurements, such as those from remote probes, often include the entire internet path and intermediate network hops, making them unsuitable for assessing the cable's performance directly. For example, measurements like "Minsk to Hermosa Beach: min 1.9 ms" are artifacts caused by rate-limited ICMP replies and fall below the physical latency floor, indicating they are not representative of the cable's actual performance.

Redundancy: what happens if it breaks

ACC-1 will share landing points with numerous other submarine cables, providing redundancy in case of outages. For example, Alupang in Guam is also served by the Bifrost cable, while Batam hosts over 20 other cables, including Apricot, Asia United Gateway East, and Indonesia Global Gateway. Similarly, Hermosa Beach in the United States connects to cables such as JUPITER, SEA-US, and Southern Cross NEXT. In the event of a break, traffic can be rerouted through these alternative systems. However, repair logistics for submarine cables can be complex, involving specialized cable-laying ships, favorable weather conditions, and coordination with regulatory authorities.

Bottom line

• ACC-1 is a planned submarine cable system connecting Asia-Pacific and the United States, expected to be ready for service in 2028.
• Owned by Inligo Networks, the cable spans approximately 19,000 km and has ten landing points across diverse regions.
• Key technical details such as design capacity, fiber pairs, and supplier have not been disclosed.
• The theoretical round-trip latency for the wet segment is approximately 186.3 milliseconds, though real-world performance will be higher.
• Redundancy is supported by numerous alternative cables at shared landing points.
