Relativity Networks Secures $22M in Funding To Speed Up AI Data Center Fiber Connectivity
aiinsider ·
Relativity Networks has raised $22 million in SAFE note funding from Rhapsody Venture Partners, Bell Ventures, and Faster Than Glass, and also secured a separate $40 million follow-on order from an unnamed hyperscaler. The company develops hollow-core fiber technology that transmits light through a vacuum chamber rather than glass, enabling data transmission roughly 50 percent faster than conventional fiber. CEO Jason Eichenholz said the technology could reduce signal travel time from about five microseconds per kilometer to roughly three and a half, a difference that grows more significant as AI compute clusters spread across larger physical distances. The technology is particularly suited to multi-campus deployments, where separate facilities must operate as a single synchronized system despite being built near available power rather than near one another. Eichenholz framed this as an emerging shift in AI infrastructure optimization, moving from earlier focuses on raw compute and internal networking toward optimizing geography itself to expand the distances developers can span before latency becomes limiting. This development comes amid projections that the data center industry will spend up to $4 trillion by the end of the decade.
