Largest-capacity submarine cable system in Vietnam becomes operational

The Asia Direct Cable (ADC) is an undersea fiber optic cable system that spans approximately 9,800 kilometers, connecting Vietnam, China, Hong Kong (China), Thailand, the Philippines, Singapore, and Japan. Notably, it connects to three major data hubs of Asia, namely Singapore, Hong Kong and Japan.

Asia Direct Cable (ADC), a fiber-optic submarine cable with a capacity of 50 Tbps – the largest in Vietnam, was put into operation in early April, according to the Viettel Military Industry and Telecoms Group.

The ADC's capacity is equivalent to 125% of the total international connection capacity of the five existing submarine cable systems (IA, AAE-1, APG, AGG, and SMW-3). It also boasts higher speeds compared to previous systems.

Viettel, the sole Vietnamese investor in the project, owns the entire submarine branch, the landing station in Quy Nhon city in the central province of Binh Dinh, and a part of the main international route.

With a total investment of 290 million USD, the route is the result of the collaboration of nine leading telecommunications corporations: Viettel (Vietnam), Softbank (Japan), Tata (India), Singtel (Singapore), China Telecommunications Corporation, China Telecom Global, China Unicom (China), National Telecom (Thailand), and PLDT (the Philippines)./.
