Fujitsu Limited, its network subsidiary 1Finity, and Arrcus signed a strategic partnership agreement aimed at advancing next-generation networking infrastructure for AI-driven environments. The collaboration targets the growing demand for high-performance connectivity across data centers, cloud platforms, 5G/6G networks, and edge deployments as AI workloads drive exponential increases in data traffic.
Under the agreement, 1Finity will offer Arrcus networking software and solutions as part of its portfolio and jointly develop global go-to-market initiatives. The companies plan to focus initially on Japan while expanding globally to serve telecom operators, enterprise customers, and data center providers. The partnership also includes joint development of integrated solutions covering network design, deployment, operations, and managed services.
Arrcus provides a disaggregated networking stack built around its ArcOS network operating system, which runs on merchant silicon and white-box hardware. The software operates across environments from edge infrastructure to multi-cloud data center clusters and enables centralized management without requiring proprietary hardware platforms. According to Arrcus, deployments using its software have achieved more than 40% reductions in total cost of ownership across several networking use cases.

“Flexible networks that combine innovation in software, silicon, and optics are of critical importance for AI data centers and 5G/6G connected inference edges. We are excited to partner with Fujitsu and 1Finity to bring our combined strengths to enterprises, service providers, and cloud operators worldwide,” said Shekar Ayyar, Chairman and CEO of Arrcus.
🌐 Analysis
This partnership reflects a broader shift toward disaggregated networking architectures in AI infrastructure. Hyperscalers and cloud providers increasingly favor merchant silicon switches and software-defined network operating systems that run across white-box hardware, allowing them to optimize performance, cost, and supply chain flexibility compared with traditional vertically integrated networking platforms.
Fujitsu’s involvement also highlights the growing role of optical interconnect and AI-optimized compute platforms in large-scale AI clusters. Through 1Finity’s optical transport portfolio and Arrcus’ routing software, the companies aim to address both scale-out data center fabrics and wide-area interconnects linking AI training clusters, cloud regions, and edge inference environments.
