WhiteFiber announced successful R&D results for a cross-data-center distributed GPU supercluster achieving 111.2 Tbps th

WhiteFiber, Inc., a leading AI infrastructure provider, announced initial R&D testing results for its cross-data-center networking solution on July 9, 2026. The proprietary distributed GPU supercluster architecture achieved 111.2 Tbps across 83 kilometers of dark fiber, roughly double the capacity of comparable published full-spectrum field trials while using only a portion of available fiber spectrum. The guaranteed round-trip latency of 0.9 milliseconds sits within 8 percent of the physical limit for light traveling through fiber over that distance. Full-fiber lighting testing is planned prior to commercial launch in 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 rather than two connected environments. This 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.

The project 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. While the distributed architecture was used for R&D and demonstration, the technology has applications beyond this use case, including telecommunications, edge computing, and sovereign AI.

Sam Tabar, Chief Executive Officer of WhiteFiber, stated: "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, added: "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."

WhiteFiber will share additional details about availability, architectural design, and pricing in conjunction with the Q3 2026 commercial launch.
