Vietnam to amp up subsea cables

28 June 2024

Vietnam’s international fibre optic cable system could see the addition of at least ten new undersea cables by 2030, bringing the number of Vietnam's undersea routes to at least 15.

Four will reportedly be up and running by 2027, bringing the total capacity to at least 134Tbps. For the period 2028-30, at least six new undersea fibre optic cable routes will increase the total design capacity of marine fibre optic cables in Vietnam to a minimum of 350Tbps. In both cases at least one of the routes will be owned by Vietnam.
The strategy has been approved by the Ministry of Information and Communications (MIC). It aims to make Vietnam an important link in regional and international digital infrastructure and data transmission.

At least two more international terrestrial fibre optic cable lines are also planned by 2030, ensuring that the total capacity on land is at least 15% of the actual used capacity of the marine system. Reports say that the country will maintain at least Singapore, Hong Kong and Japan as the main digital hub connections, while periodically reviewing and evaluating digital hubs to add appropriate connection points.

Vietnam currently has five international undersea fibre optic cable lines with total available capacity of 34Tbps. It also has two land cable lines connecting to Hong Kong and Singapore with a total capacity of 5Tbps.
