Viettel Business Solutions Corporation, representing Viettel Group (Viettel), and Singapore Telecommunications Limited (Singtel) have signed an Memorandum of Understanding (MOU) to collaborate on deploying the Vietnam - Singapore Cable System (VTS) directly connecting Vietnam and Singapore. The agreement was signed in Nha Trang, Vietnam, on Arpil 11, 2024.

This marks a significant milestone for Viettel in its efforts to implement the “Development Strategy of Vietnam's International Optical Cable System by 2030, vision to 2035” of the Ministry of Information and Communications (MIC). With the goal of becoming a regional data centre (Digital Hub), Vietnam's international optical cables are identified as a critical component of the digital infrastructure that must be invested first in to ensure Vietnam's international connectivity with super-large capacity, ultra-wide bandwidth, sustainability, greenness, intelligence, openness and security to promote the national's digital transformation, digital economy, digital society and international integration.

Under the agreement, both parties plan to deploy the submarine cable system having its trunk to connect Vietnam to Singapore (VTS cable) with a configuration of 8 fibre pairs (8 FPs), using the most advanced wavelength division multiplexing technology available today.

The main trunk landing station is in Vietnam (managed by Viettel) and Singapore (managed by Singtel). Additionally, the VTS cable is expected to have branch landing stations in Cambodia, Thailand, and Malaysia. The VTS cable is scheduled to be operational in the second quarter of 2027.

Thus, VTS will become the first cable jointly established by the two largest operators in Vietnam and Singapore, promising to be the shortest cable directly connecting Vietnam to the largest Digital Hub in Asia, Singapore, with the most advanced bandwidth and technology. The deployment of this cable system is in line with Vietnam's strategy for developing its international optical cable system by 2030, with a vision to 2035. When put into operation, the cable will add hundreds of Tbps to Viettel's total international connectivity capacity, contributing to providing a large amount of high-speed capacity, opening up a new connection direction to the South, and enhancing the redundancy and security of Viettel's international connection infrastructure.

According to this strategy, by 2030, Vietnam needs to increase the total number of submarine cables to a minimum of 15 ones with a total capacity of at least 334 Tbps, of which there should be at least 2 submarine cable systems established by Vietnam going into operation, with priority given to short routes directly connecting to major Digital Hubs in the Asia region. Furthermore, the submarine cable system should be deployed evenly in all three directions: connecting to the North of the East Sea; connecting to the South of the East Sea; connecting to the Southern sea area.

Recognising its role, Viettel has closely followed the strategic direction of submarine cables set by the MIC to develop and propose the implementation of submarine cable projects with a vision to 2030, aiming to meet the capacity needs, ensure safe connection for Viettel's network in all circumstances in particular, and ensure national information security in general. Among these projects, the Vietnam-Singapore Cable System (VTS) is a key target for Viettel.

With investment in and ownership of new submarine cables, Viettel expects to play a significant role as a crucial link in the digital infrastructure and international and regional data transmission infrastructure, deploying international Internet connection applications requiring high-speed connection such as: 5G, Internet of Things (IoT), Automation, Artificial Intelligence (AI) and Virtual Reality (AR/VR). Additionally, Viettel will ensure the safety and redundancy of its network, ensuring the quality of internet services and other international connection services, as well as national information security.

Prior to this, Viettel announced the investment in Asia Direct Cable (ADC), the largest bandwidth cable system in Vietnam, with connections to all three largest IP Hubs in Asia (Hong Kong, Japan, Singapore), and Viettel owns the landing station of this cable in Quy Nhơn. Viettel is also the largest investor in The Asia Link Cable (ALC), connecting to the two main IP Hubs in Asia (Hong Kong, Singapore), and owns the landing station of this cable in Đà Nẵng
