Relativity Networks has raised $22 million to bring hollow-core fiber technology to data centers, aiming to make high-speed networking faster and more efficient for the next generation of compute infrastructure.
Unlike conventional fiber, hollow-core fiber guides light through an air-filled core, allowing data to travel at significantly higher speeds. According to the company, the technology can transmit data about 30% faster than standard fiber, a meaningful improvement for latency-sensitive environments.
Why this matters for AI
As AI models and applications grow, data centers need to move enormous amounts of information between servers, storage, and accelerators. Faster fiber could help reduce bottlenecks and improve the responsiveness of AI infrastructure.
- Lower latency: Faster transmission can improve communication between data center systems.
- Better scalability: More efficient networking supports increasingly demanding AI workloads.
- Infrastructure innovation: The funding signals growing investment in the physical foundations of AI progress.
While hollow-core fiber remains a rarely deployed technology today, Relativity Networks’ new funding could help move it closer to broader real-world adoption in modern data centers.
