Relativity Networks raises $22 million for faster data-centre fibre

Summary

Relativity Networks announced $22 million in SAFE funding and a further$40 million order from an unnamed hyperscaler, TechCrunch reported. Its hollow-core fibre is designed to cut propagation latency to about 3.5 microseconds per kilometre, compared with roughly 5 microseconds for conventional fibre.

Why it matters

As AI clusters spread across multiple campuses, optical latency and interconnect design are becoming material constraints on inference performance and infrastructure economics.
