WhiteFiber announced initial R&D testing results forit's cross-data-center networking solution, a proprietary distributed GPU supercluster architecture.
Initial testing achieved 111.2 Tbps across 83km of dark fiber, already roughly double the capacity of comparable published full-spectrum field trials, using only a portion of available fiber spectrum. Guaranteed round-trip latency of 0.9ms sits within 8% of the physical limit for light in fiber over that distance. Full-fiber lighting testing is planned prior to commercial launch in Q3 2026.
R&D results confirm industry-first commercial distributed GPU supercluster architecture; commercial launch targeted for Q3 2026
The cross-data-center networking solution links two geographically separated data centers into a single logical GPU supercluster operating as one unified system, not two connected environments. The architecture enables enterprises to run AI workloads that exceed the scale, resilience, and compliance capabilities of any single facility. WhiteFiber has submitted patent applications for the underlying implementation.
While the distributed architecture was used for R&D and demonstration, this technology has applications beyond this use case, including telecommunications, edge computing, and sovereign AI.
It was built in collaboration with DriveNets, which provides the high-performance network fabric connecting both sites, and WEKA NeuralMesh, which provides high-performance data and memory infrastructure across the cluster.
Sam Tabar, Chief Executive Officer of WhiteFiber
These results validate what we set out to prove: that geographic distance does not have to be a constraint on AI infrastructure. This is the foundation for a new class of AI compute, one that delivers the performance of a single supercluster with the resilience and flexibility of a distributed system. We are excited to bring this capability to market.
Tobias Ford, Principal Design Engineer at WhiteFiber
Achieving 111.2 Tbps with sub-millisecond latency across 83 kilometers is the result of months of precise, disciplined engineering. Every element of this system was designed and validated to perform at this level.
Liran Zvibel, Co-founder & CEO at WEKA
WhiteFiber's distributed cluster technology has the potential to reshape how AI infrastructure is deployed. WEKA is proud to support this project as WhiteFiber's AI infrastructure partner. Together, we are helping deliver a full-stack solution designed to give customers ultra-low latency, flexibility, and resilience at scale.
Yossi Kikozashvili, VP Product Management, AI at DriveNets
What WhiteFiber has built demonstrates what becomes possible when you pair the right networking architecture with genuine engineering ambition. Our Ethernet-based fabric supports the highest performance in the most demanding, high-bandwidth, low-latency environments, ensuring optimized utilization of GPU and power resources in a scale-across supercluster architecture. These results are a direct reflection of that.
