Our Technology
What do you mean, we changed the speed of light in fiber optics?
After a decade of investment, development, and innovation, Relativity Networks’ Hollow Core Fiber (HCF) has unlocked new possibilities in data transmission. Our breakthrough began with pioneering research at the University of Central Florida, where we unlocked a way to make light travel faster through optical fiber than ever before possible. We then transformed this scientific achievement into a practical reality by optimizing it for large-scale manufacturing.
Our proprietary anti-resonant designs create an advanced optical waveguide. Made of precision-engineered glass walls so thin they’re invisible to the human eye, these structures create mirror-like boundaries that confine light and guide it through an air core with unmatched speed and minimal power loss.
In a world where data centers can’t afford downtime, HCF enables seamless backups and uninterrupted connections, making it the ideal solution for the demands of the cloud computing and AI era.

How it works
Why Air Changes Everything
For decades, data transmission has relied on traditional fiber optics, where light moves through glass. But glass is far from perfect — it slows light down and distorts the signal due to nonlinearities and dispersion.
Hollow Core Fiber redefines what’s possible. By replacing glass with air and adding precision-engineered anti-resonant structures, HCF creates a near-perfect mirror that propels light with unmatched speed and efficiency.
The result? Data now moves nearly 50% faster — unlocking the full potential of light-speed data transmission.
Unlocking 2.25x More Buildable Space
With traditional fiber, urban grids have reached their limits. Power constraints, high costs, and inflexible infrastructure have left hyperscalers competing for limited resources — and AI demands more.
Beyond these crowded zones lies open space and renewable energy opportunities. Traditional fiber optics can’t reach these areas without compromising performance — but HCF can.
HCF unlocks 2.25x more buildable space and extends traditional latency thresholds from 60 km to 90 km, enabling data centers to grow where power and land are available — without sacrificing speed or reliability.
