# Startup raises $22M for faster data center fiber tech

*2026-08-19 · Source: [TechCrunch](https://techcrunch.com/2026/08/19/relativity-networks-raises-22-million-to-bring-a-faster-kind-of-fiber-to-data-centers/)*

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.

**Topics:** infrastructure, business
