Relativity Networks raises $22M for hollow-core fiber technology to speed data centers
Key points
- Relativity Networks raised $22 million in SAFE note funding.
- A hyperscaler placed a $40 million follow-on order.
- Hollow-core fiber transmits data 30% faster than traditional fiber.
- Faster fiber reduces latency for distributed data center operations.
Funding for Faster Fiber
Relativity Networks announced $22 million in SAFE note funding from Rhapsody Venture Partners, Bell Ventures Inc., and Faster Than Glass LLC. This investment method is standard for pre-seed and seed rounds. The company also received a $40 million follow-on order from an unnamed hyperscaler.
Hollow-Core Fiber Technology
Relativity Networks specializes in hollow-core fiber, a technology that allows data transmission 30% faster than conventional fiber. Unlike traditional fiber, which uses glass, hollow-core fiber transmits light through a vacuum chamber, bringing it closer to the theoretical speed of light. This reduces signal travel time from approximately five microseconds per kilometer to three and a half microseconds.
Impact on Data Center Latency
The increased speed of hollow-core fiber addresses growing latency challenges in large-scale data center operations. As AI compute scales across multiple buildings and campuses, the physical distance between GPUs increases. Faster fiber allows these distributed systems to operate more cohesively, effectively extending the distance data can travel before latency becomes a significant issue. This could enable data centers to span 30% larger distances without performance degradation.
Addressing Spatial Constraints
This technology offers a solution to the spatial constraints impacting data center development. By reducing latency, Relativity Networks' fiber allows for more geographically dispersed data center components to function as a single unit. This enables companies to utilize existing infrastructure and build in locations with available power, even if they are not immediately adjacent, supporting the trend of distributing compute across multiple campuses.
