Startup raises $22M for faster data center fiber tech

Relativity Networks raised $22 million to commercialize hollow-core fiber, a rarely deployed technology. The company says it can transmit data 30% faster than conventional fiber.

Why it matters: Faster interconnects matter increasingly for AI data centers, where networking speed between clusters is becoming as important a bottleneck as compute itself. Wider adoption of hollow-core fiber could meaningfully cut latency for large-scale AI training and inference.
