Hollow-core fiber shrinks latency 30% — is this the fix for distributed AI compute?
relativity networks raised $22m for hollow-core fiber that transmits data 30% faster than glass. this lets ai data centers spread across larger distances without slowing down synchronization.
relativity networks raised $22m in safe funding for hollow-core fiber, which conducts light through a vacuum core rather than glass. ceo jason eisenholz claims this reduces transmission latency by roughly 30%, allowing signals to travel 1km in 3.5 microseconds instead of 5. this addresses a critical bottleneck as ai developers distribute training clusters across multiple campuses due to power and space constraints. the company also landed a $40m follow-on order from a major hyperscaler to deploy the technology at scale. this shift signals a move from optimizing just for gpus to optimizing network geography to enable larger distributed ai models.
