Relativity Networks secured $22 million in funding to bring hollow-core fiber technology to data centers, offering transmission speeds 30% faster than conventional fiber optics. The company plans to use the investment to deploy this rarely used technology across data center infrastructure.
Hollow-core fiber differs from traditional fiber optics by transmitting light through an air-filled core rather than solid glass. This design reduces signal interference and allows data to travel closer to the speed of light in a vacuum. While the technology has existed for years, deployment has remained limited due to manufacturing complexity and cost.
The speed advantage could prove significant for data centers handling high-frequency trading, artificial intelligence processing, and other applications where microseconds matter. Traditional fiber optics transmit data through a solid glass core, which slows light transmission compared to the air-based approach Relativity Networks is commercializing.
Data center operators have increasingly sought ways to reduce latency as computational demands grow. The 30% speed improvement from hollow-core fiber could provide a competitive edge for facilities processing time-sensitive workloads. The technology also offers potential benefits in reduced signal degradation over long distances.
Relativity Networks joins a small group of companies attempting to commercialize hollow-core fiber beyond research settings. The $22 million funding round signals investor confidence that the technology can overcome previous deployment barriers and find practical applications in modern data infrastructure.
