Relativity Networks Bets on Hollow-Core Fiber to Revolutionize Data Centers

View original source

Relativity Networks is making waves in the data center industry by betting on hollow-core fiber technology to improve data transmission speeds. This innovation can potentially reshape how data centers are geographically distributed as companies plan to spend an estimated $4 trillion by the end of the decade on data center developments.

  • On Tuesday, the company announced it had raised $22 million in SAFE note funding, with contributions from Rhapsody Venture Partners, Bell Ventures Inc., and Faster Than Glass LLC.
  • Additionally, Relativity Networks secured a $40 million follow-on order from an unnamed leading hyperscaler.
  • Hollow-core fiber allows for data to be transmitted 50% faster than current traditional fiber by using a vacuum chamber instead of fiber-optic glass.
  • The company's CEO, Jason Eichenholz, claims the use of this technology could reduce signal latency significantly, from five to three and a half microseconds per kilometer.
  • This improvement opens up opportunities for multi-campus deployments, enabling synchronized operations across sprawling data center complexes.
  • Eichenholz predicts that this could represent a third era of AI development focused on optimizing geography, as companies need to distribute computing power efficiently amidst increasing spatial and power-grid challenges.
