In order to ensure the annual growth rate of bandwiths and to make up for the undersea fiber optic cables that are frequently broken, Viettel will deploy 4 more undersea cable routes from now to 2030, of which the ADC route has been completed. It is expected to be put into operation in 2023, contributing to increasing the international internet connection capacity by 18 Tbps, three times higher than the current one. Viettel's international connection capacity is currently nearly 9 Tbps.

In addition, Viettel always reserves 40% of its international capacity to be ready for situations of undersea fiber optic cable issues, avoiding affecting the customers’ experience. When there is a high load, the information technology systems built by Viettel's own personnel will automatically balance the load, route and regulate capacity on the remaining undersea and land cable directions.
