In the context of the global economy entering a period of accelerated digitalization, telecommunications infrastructure – especially international fiber optic cables – has become a key factor in determining a country’s technological position. For Vietnam, upgrading and expanding the fiber optic network, both at sea and on land, not only serves domestic needs but also paves the way for the country to become a regional data connection center. Recognizing this, DCH Group is gradually realizing a strategic roadmap, with the goal of building a large-scale international fiber optic cable system, including both sea and land routes, to serve the new generation of AI data centers that DCH is deploying in Ba Ria – Vung Tau.

The core of DCH's plan is the construction of a submarine fiber optic cable landing station in Vung Tau City, which has special geographical advantages: close to international shipping routes, where logistics and energy infrastructure are well-planned. From this landing station, DCH will deploy an undersea cable system connecting directly to major data centers in the region such as Singapore, Malaysia and Japan. In particular, the Vietnam - Singapore - Malaysia route is identified as a priority route, playing a backbone role in connecting Southeast Asia. The route to Japan will open the door to direct data trade with developed digital economies such as Tokyo and Osaka, while reducing the load on existing routes that are already overloaded or frequently experiencing problems.

Not stopping there, DCH also pays special attention to diversifying connection directions, in order to increase redundancy, improve reliability and ensure stable data flow. Therefore, in addition to the submarine cable route, DCH is promoting the deployment of international fiber optic cable routes on land. An important direction is the connection route through China, through Lang Son or Mong Cai border gates, helping Vietnam connect directly with China's digital infrastructure - a country that owns the largest technology ecosystem in the world, and is also a giant data transit point connecting Asia with Europe.
The second land route is the fiber optic cable route through Cambodia, connecting Ho Chi Minh City to Tay Ninh and through Cambodia and is expected to go further to Bangkok (Thailand). This route not only acts as a complementary connection channel to the sea routes but also expands the connectivity with emerging economies in the Mekong region. Land connections through neighboring countries not only bring strategic benefits in spreading network risks, but also lay the foundation for Vietnam to act as a regional data transit point, participating more deeply in the global digital value chain.
All connection routes – both sea and land – will be integrated directly into DCH's modular data centers, which are being invested in and built according to Tier 4 international standards in Ba Ria - Vung Tau province. Direct connection helps to significantly reduce signal latency, while optimizing operating costs and enhancing security. These cable routes will use the latest optical transmission technology, supporting bandwidth of tens of terabits per second, with the ability to flexibly expand and operate stably in harsh environments. In particular, DCH will apply a "Carrier-neutral" connection infrastructure management model, creating conditions for international network operators, businesses and digital platforms to easily participate in exploitation, channel leasing, and establishing transit points in Vietnam.
The implementation roadmap is clearly divided into phases. From the end of 2025 to mid-2026, DCH will focus on completing the landing station and putting into operation the first fiber optic cable connecting through the international gateway in Tay Ninh through Cambodia to deploy the provision of transmission-related services in Vietnam as well as international connections.
After the first step, the next step will be to deploy submarine optical cables to Japan, Malaysia, Singapore, etc. and at the same time deploy land connections through China, gradually forming a circle connecting the Asia-Pacific region with the data center in Vietnam playing the central role.
With a well-planned investment strategy, advanced technology and regional vision, DCH is not only building a simple fiber optic cable system, but is also creating a digital infrastructure of intercontinental nature, opening up new development space for digital economy, cloud computing, artificial intelligence and cross-border services. This is a strong step, contributing to enhancing Vietnam's competitiveness on the global digital economic map - where data is the most valuable resource of the era.
