Asia Connect Cable-1 (ACC-1)

Overview

Asia Connect Cable-1 (ACC-1) is a submarine cable system spanning approximately 19,000 kilometres across the Indo-Pacific region. It connects Australia, Guam, Indonesia, the Philippines, Singapore, Timor-Leste, and the United States, forming a broad intra-regional and transoceanic corridor linking Southeast Asia, Oceania, and the North American Pacific coast.

Route and Landings

In Australia, the cable lands at Darwin, Northern Territory. In Guam, it reaches shore at Alupang. Indonesia hosts four landing points: Batam, Jakarta, Makassar, and Manado. The Philippines is served by a landing at Davao. Singapore has a landing in the city of Singapore itself. In Timor-Leste, the cable comes ashore at Dili. The United States landing is at Hermosa Beach, California.

Ownership and Operators

ACC-1 is wholly owned by Inligo Networks. Inligo Networks is a privately held submarine cable developer focused on building independent capacity across the Asia-Pacific region.

Technical Profile

The system extends across 19,000 kilometres of sea floor, connecting ten landing stations across seven countries. No supplier or fiber-pair configuration has been announced at this stage.

Status and Timeline

ACC-1 is planned for service with a target ready-for-service date of 2028. The system is not yet in operation and is currently in the development phase.

Regional Context

The corridor ACC-1 will serve already carries several established cable systems. EAC-C2C and Southern Cross Cable Network have connected parts of this region since the early 2000s, while PEACE Cable added Singapore-anchored capacity in 2022. Project Waterworth is a forthcoming system also linking Australia and the United States, at a considerably longer route length of 50,000 kilometres. At 19,000 kilometres, ACC-1 is a more compact system by comparison, but distinguished by its concentration of landings within Indonesia and its direct connection to Timor-Leste, a territory with limited existing cable infrastructure. Measured round-trip latency through the cable over recent testing averages 124.0 milliseconds, with a best recorded result of 118.7 milliseconds.

Strategic Role

With ten landing points distributed across seven countries, ACC-1 will provide direct submarine connectivity to several locations that have fewer cable options today. Indonesia's four landings — at Batam, Jakarta, Makassar, and Manado — spread access across the archipelago from west to east. The Dili landing in Timor-Leste and the Davao landing in the southern Philippines extend the system's reach into areas underserved by current cable infrastructure. The Hermosa Beach landing ties the system into the established North American Pacific cable hub, while Darwin and Guam serve as stepping-stone nodes within the broader Indo-Pacific network.
