Fujitsu, Chunghwa Telecom, and Fujitsu Group’s 1FINITY have agreed on a strategic collaboration for the social implementation of next-generation telecommunications infrastructure in Taiwan. This partnership aims to provide innovative solutions that combine optical and quantum technologies to address the increasing data traffic and power consumption challenges brought about by the full-scale arrival of the AI era.

Agreement on a strategic partnership among the three companies

Fujitsu Limited, Fujitsu Group’s 1FINITY Corporation, and Taiwan’s largest telecommunications operator, Chunghwa Telecom Corporation, agreed on July 22, 2026, a two-year strategic partnership for the social implementation of the All-Photonics Network (APN) and the utilization of quantum technology in Taiwan. This collaboration aims to address serious infrastructure challenges such as the explosive increase in data traffic driven by the rapid spread of artificial intelligence (AI) technology, and the resulting sharp rise in power consumption. Specifically, research will be underway to verify APN technology utilizing Chunghwa Telecom’s extensive submarine cable system and to develop network control technologies aimed at realizing distributed data centers. Fujitsu and 1FINITY will directly introduce advanced optical transmission technology cultivated through collaborations with domestic Japanese telecom carriers and their experience in building global networks directly to the Taiwanese market, aiming for the early expansion of next-generation communication infrastructure,,。 This will establish an extremely low-latency and highly efficient communication environment across Taiwan, and innovation is expected in various fields such as smart manufacturing, advanced medical services, and quantum-safe communications,,。 The following photos show the situation at the time of the announcement of this agreement.

Ongoing collaboration and evolution from 2024 onwards

This partnership represents a deepening of efforts that continue since the first strategic partnership between Fujitsu and Chunghwa Telecom on January 31, 2024. From 2024 to 2026, both companies have continued joint discussions and validation within Taiwan to build an APN based on the IOWN concept,,。 Over the past two years, we have steadily achieved results in confirming the feasibility of implementing the photonics system provided by Fujitsu and in formulating network configurations suited to Taiwan’s unique communication conditions. With the new agreement for 2026, the addition of 1FINITY, a company specializing in network operations, will further accelerate efforts to expand optical networks,,。 1FINITY is a specialized group specializing in the design, construction, and operation of open optical transmission and wireless networks, and its technological capabilities play an essential role in realizing large-capacity, low-power communication infrastructure connecting distributed data centers. The strong collaboration built over the past several years is moving beyond mere technical validation to a full-fledged phase of social implementation with a focus on real-world commercial use,,。

Technological Innovation: The Fusion of APN and Quantum Technology

The value provided by the All-Photonics Network

All-Photonics Network (APN) is a technology that uses optical signals across all areas of communication networks, boasting performance far surpassing traditional communication technologies involving electrical signal conversion. The greatest features of APN are summarized in three points: ultra-large capacity transmission, low power consumption, and ultra-low latency. In fact, in 2024 verification by Chunghwa Telecom and NTT, they achieved a transmission speed of 100Gbps and an astonishing low latency of just 17 milliseconds over approximately 3,000 kilometers of international optical fiber connecting Taiwan and Japan. In this collaboration with Fujitsu, by integrating this APN technology into Taiwan’s core infrastructure, we will build a foundation that supports advanced AI processing and remote operation technologies that require real-time capabilities, while significantly reducing power consumption during communication. In particular, the approach of maximizing energy efficiency by minimizing conversion to electrical signals is also crucial for corporate ESG (Environmental, Social, and Governance) strategies. APN is positioned as a core technology for realizing a sustainable digital society in the AI era. The diagram below illustrates the concept of next-generation networks realized by APN.

Next-generation network control utilizing quantum technology

A notable aspect of this partnership is that, in addition to expanding APN, the use of quantum technology is clearly stated. Quantum technology not only accelerates complex calculations that were difficult for conventional computers but also enables the realization of “quantum-safe communication,” which dramatically enhances communication security. The three companies will jointly explore the possibility of applying quantum technology to network control of distributed data centers using APN. A distributed data center is a system that connects multiple sites with a high-speed optical network, rather than aggregating data into a single massive site, utilizing the entire system as a single massive computing resource. At this time, by protecting and controlling communication between sites with quantum technology, an infrastructure with extremely robust resistance to cyberattacks is built. Fujitsu is building a hybrid quantum computing platform and developing technologies to automatically optimize computation time and costs, and these insights will be utilized to advance Taiwan’s telecommunications network. The fusion of quantum technology and APN is not just about speeding up communications; it serves as a strategic stepping stone to ensure resilience and security as a critical national infrastructure.

Management and Market Background and Future Outlook

Infrastructure Challenges in the AI Era and Fujitsu’s Strategy

As of 2026, the world has entered an era where the emergence of a “multipolar world” and the accompanying securing of technological sovereignty are increasingly important. Especially with the boom in AI agents, the demand for computing resources in companies and municipalities has reached an unprecedented level, making it urgent to build smart security and resilient supply chains to meet these needs. Fujitsu is developing its business brand “Uvance” as part of its global strategy, and is expected to achieve consolidated sales of 3.5 trillion yen (approximately 23 billion dollars) for the fiscal year ending March 2026, making it one of Japan’s top digital service companies. For Fujitsu, the collaboration with Chunghwa Telecom marks a significant milestone in integrating its five key technologies—AI, computing, networking, data, and security—to realize sustainable social transformation (SX). Furthermore, from the perspective of base station vendors, as global vendors like Ericsson and Nokia rise, establishing a unique advantage through advanced technologies like Open RAN and APN is extremely important from an economic security standpoint.

Roadmap for next-generation communications starting from Taiwan

Looking ahead, the three companies have designated the four-year period from fiscal 2026 to fiscal 2029 as the acceleration period for social implementation. This aligns with the adoption of joint proposals under the Ministry of Internal Affairs and Communications’ initiative for “Research and Development to Expand Radio Resources,” and alongside research projects involving Fujitsu, Docomo, NTT, and others, aims to establish global technical standards and secure leadership. In Taiwan, concrete technical validation utilizing Chunghwa Telecom’s submarine system is being conducted first, and demonstration tests aimed at the practical implementation of distributed data centers are being repeated. The insights gained through this initiative will contribute to future international standards in the 6G (sixth-generation mobile communication system) field and be designed with an eye toward technology deployment throughout Asia. Through this collaboration, Chunghwa Telecom aims to quickly provide Taiwanese society and people with smart information and communication services equipped with deterministic network performance and quantum security. The 2026 partnership will mark a decisive step toward Taiwan’s evolution into a world-leading hub for the next-generation digital economy,,。
