The explosion of artificial intelligence, cloud computing, and big data platforms has ushered the world into an era where data has become one of the most valuable resources. In Vietnam, a strong wave of investment in data centers (DCs) is unfolding, opening a new chapter for the nation’s digital infrastructure. Yet behind those sprawling facilities spanning dozens of hectares and server racks operating 24/7 lies a fundamental but often overlooked element: the transmission system. If data centers are the “heart” of the digital economy, then transmission networks are its “circulatory system,” ensuring data flows securely, continuously, and rapidly to every connection point. Without high-speed transmission, there can be no large-scale data centers—and no efficient AI infrastructure.
In the digital world, value doesn’t lie in where data is stored, but in how fast and how well it connects. A data center only becomes truly meaningful when it is linked to a robust transmission network capable of connecting to other systems, users, and global platforms. Today’s hyperscale data centers demand bandwidths reaching hundreds of gigabits—or even terabits—per second to support millions of simultaneous queries and processing tasks. That is why transmission infrastructure has become a decisive factor in every data center investment plan.
In Vietnam, the transmission system is being upgraded at an unprecedented pace. The North–South fiber optic backbone, international undersea cables, and backhaul networks connecting high-tech zones are rapidly expanding, enabling cross-regional and cross-border data transfer with ultra-low latency. This advancement underpins strategic projects such as DCH’s Digital HUB in Bà Rịa – Vũng Tàu, a flagship data center strategically located near national fiber routes and international landing points. The location allows it to leverage maximum bandwidth capacity while serving as a data gateway connecting Vietnam to the world.
In the race for digital infrastructure, transmission speed is not merely a technical metric—it’s a strategic advantage. Global technology giants choose their data center locations based on transmission capabilities: the closer to national backbones and international exchange points, the stronger the competitiveness in cost, latency, and scalability. With its geographic advantages and rapidly growing telecom infrastructure, Vietnam is poised to become a new data transit hub in Southeast Asia.
The transformation is not only about scale but also about technology. From traditional SDH or MPLS networks, Vietnam’s infrastructure is shifting toward advanced solutions like IP-over-DWDM, high-speed Ethernet, and software-defined networking (SDN). These technologies enable smarter, self-optimizing, and near real-time adaptive routing and bandwidth management—crucial for the stable, flexible operations that modern AI and edge computing applications demand.
Beyond technology, transmission also carries strategic significance for data sovereignty. As nations tighten control over their data, robust domestic transmission infrastructure enables Vietnam to better manage data flows, ensure information security, and foster local data storage and processing. When Vietnamese data is transmitted and processed within national infrastructure, it not only drives economic value but also strengthens national digital security.
The Digital HUB project by DCH exemplifies this trend—combining data center investment and transmission infrastructure within a unified strategic vision. Beyond building a large-scale facility, DCH aims to create a new “data highway” where enterprises, organizations, and digital service providers can interconnect directly, reducing latency and optimizing transmission costs. This model mirrors successful international practices where interconnected data center clusters form national data backbones.
In the near future, transmission will evolve beyond a data conduit to become an intelligent, self-learning platform capable of adapting dynamically to demand. As AI and edge computing continue to advance, transmission infrastructure will play a defining role in shaping the “flow of data” across the economy. That’s why, to build hyperscale data centers, Vietnam must invest in ultra-broadband transmission, multi-route international connectivity, and policies encouraging private sector infrastructure investment.
Data only holds value when it moves—swiftly, securely, and reliably. And it is the transmission infrastructure, though often invisible, that determines Vietnam’s capacity to integrate into the global digital economy. As these “data arteries” expand, as intercontinental cables connect, and as modern data centers come online, Vietnam is not just building technology infrastructure—it is laying the foundation for a sovereign, intelligent, and globally connected digital future.
