Operating the largest capacity cable line in Vietnam

The Military Industry and Telecommunications Group (Viettel) owns the entire submarine cable branch connecting Vietnam and the landing station in Quy Nhon, along with part of the main international axis. Viettel Networks is the operating unit.

The total investment capital for the entire ADC line is up to 290 million USD with the cooperation of 9 leading telecommunications corporations including Viettel (Vietnam), Softbank (Japan), Tata (India), Singtel (Singapore), China Telecommunications Corporation, China Telecom Global, China Unicom (China), National Telecom (Thailand), PLDT (Philippines). Viettel is the only unit in Vietnam participating in investing in this cable line.

The cable route meets the needs of AI and 5G deployment and is ready for any incident.

ADC is an undersea optical cable system with a length of about 9,800 km, connecting 7 countries and territories including Vietnam, China, Hong Kong, Thailand, Philippines, Singapore and Japan.

Compared to Vietnam's existing submarine cable lines, ADC has the unique feature of directly connecting to all three Internet centers in Asia: Singapore, Hong Kong and Japan.

The maximum capacity of ADC is 50Tbps, the largest in Vietnam and equal to 125% of the total international connection capacity of all 5 active submarine optical cable lines (IA, AAE-1, APG, AGG, SMW-3). ADC also has a higher speed than previous systems.

The ADC route demonstrates Viettel’s commitment to building a modern digital infrastructure in Vietnam. In the immediate future, Viettel will use a portion of the capacity on the ADC route to enhance international connectivity, meet new data demands, and enhance customer experience when using Internet services.

With ADC, Viettel increases the international connection reserve, increases the number of cable routes and international connection directions, ensuring Vietnam's connection needs when there is a submarine optical cable break.

ADC not only helps ensure network security, but also strengthens digital infrastructure to meet services requiring high speed and large bandwidth such as AI, 5G, Bigdata, AR/VR.
