Relativity Networks raises $22 million to bring a faster kind of fiber to data centers

A company has raised funding to deploy hollow-core fiber in data centers, a technology that transmits data 30% faster than conventional fiber by sending light through a vacuum chamber rather than through glass. As artificial intelligence systems grow larger and require computing resources spread across multiple buildings and campuses, the speed advantage of this faster fiber becomes significant, potentially allowing data center developers to space their infrastructure farther apart before latency becomes a problem. Data center developers are spending heavily on expansion but face constraints from power grids and geography, so any technology that effectively extends the usable distance between computing resources could alter where and how these facilities are built.
