Relativity Networks raises $22 million to bring a faster kind of fiber to data centers
Relativity says hollow-core fiber could let AI data center campuses operate over longer distances without the same latency penalty.
The company announced $22 million in SAFE note funding and a $40 million follow-on order from an unnamed hyperscaler. Its fiber sends light through a vacuum chamber rather than glass, which CEO Jason Eichenholz says cuts roughly five microseconds per kilometer to about three and a half. TechCrunch frames the pitch around AI buildouts spreading across multiple buildings or campuses as power and site constraints tighten. TechCrunch AI's note
