Accton/Edgecore, 1Finity, and Liqid Team Up on All-Photonic Datacenter Fabric for Wide-Area AI Scaling
Accton/Edgecore, 1Finity (a Fujitsu company), and Liqid unveiled a joint all-photonic datacenter architecture at SC25 in St. Louis, targeting seamless connectivity across distances spanning a few kilometers to several hundred kilometers. The design links RDMA and NVMe-oF workloads with no throughput degradation, while maintaining stable transmission rates and low latency for AI, HPC, and real-time applications.
The collaboration integrates open networking switches, wavelength-programmable optical systems, 800G ZR/ZR+ coherent pluggables, and PCIe Gen5 composable infrastructure to support resource pooling across racks, campuses, and multi-site datacenters. The companies are positioning the platform for operators scaling AI clusters that must dynamically allocate GPUs, FPGAs, memory, and storage over a high-bandwidth optical fabric.
The unified solution uses Accton/Edgecore’s switching and optical wavelength systems, 1Finity’s P300 coherent modules and programmable NICs, and Liqid’s Matrix software-defined composability. The companies aim to extend resource sharing between geographically distributed environments, creating an adaptable fabric for AI and data-intensive workloads.
The system is being showcased at SC25 and is planned for general availability in Q4 2025.
• All-photonic, long-distance interconnect from a few km to several hundred km
• Lossless RDMA and NVMe-oF throughput across metro and regional spans
• Accton/Edgecore wavelength-switched optical layer and open networking switches
• 1Finity P300 800G ZR/ZR+ optics and programmable optical NICs
• Liqid PCIe Gen5 composable GPU/FPGA/memory/storage pooling across sites
• Dynamic scale-up/scale-out for AI, ML, and HPC workloads
• Multi-datacenter resource sharing over coherent photonic links
“As organizations scale AI from racks to global clusters, they need open networking that is powerful, programmable, and ready for anything,” said Mingshou Liu, President of Edgecore.
🌐 Analysis
This collaboration aligns with a broader industry shift toward disaggregated, photonic-first datacenter networks capable of spanning multiple sites—an architecture already explored by hyperscalers pursuing optical switching, CPO, and ZR/ZR+-enabled fabrics. Accton/Edgecore and 1Finity contribute optical reach and open networking technology, while Liqid expands the model to include PCIe-based composability across metro distances, competing with emerging Ethernet-attached disaggregation and proprietary AI fabrics.
