Relativity Networks Secures $22 Million to Accelerate Hollow-Core Fiber for Data Centers

Relativity Networks has secured $22 million in SAFE note funding alongside a major $40 million customer order to accelerate the rollout of hollow-core fiber, an optical transmission technology engineered to reduce data latency across sprawling computing campuses.

What Happened

Relativity Networks announced the close of a $22 million SAFE note financing round supported by investors including Rhapsody Venture Partners, Bell Ventures Inc., and Faster Than Glass LLC. In addition to the investment, the startup confirmed a $40 million follow-on purchase order from a major hyperscaler that chose to remain unnamed. The capital is aimed at advancing the deployment of hollow-core fiber, which sends light through a central vacuum chamber rather than standard solid glass optics.

Key Highlights

  • Relativity Networks closed $22 million in SAFE note financing from backers including Bell Ventures Inc., Faster Than Glass LLC, and Rhapsody Venture Partners.
  • A leading, undisclosed hyperscale firm committed to a $40 million follow-on order for the company’s networking hardware.
  • The firm’s hollow-core cabling transmits data roughly 30 percent faster than conventional fiber-optic glass lines.
  • According to chief executive Jason Eisenholz, the technology drops transmission time from five microseconds per kilometer to roughly three and a half microseconds.
  • Data center developers face power-grid and political constraints as total sector capital expenditures are projected to reach $4 trillion by the end of the decade.

Why This Matters

As computing requirements for artificial intelligence outgrow single GPU racks and spread across multi-building campuses spanning hundreds of acres, the physical distance between processors introduces latency. At the same time, regional power grid limitations and political factors increasingly force developers to locate facilities across separate campuses. By shaving transmission times down closer to the physical limits of light speed, hollow-core fiber allows computing systems separated by greater geographic distances to operate as a single coordinated cluster. Eisenholz noted that while earlier AI phases prioritized compute power and intra-data-center networking, the sector is entering a phase focused on geographical optimization.

What to Watch Next

Attention now turns to the delivery and implementation of the $40 million hardware order with the unnamed hyperscaler, alongside wider commercial adoption of hollow-core links across distributed data center campuses.

Frequently Asked Questions

What is hollow-core fiber?

Hollow-core fiber is an optical cabling format that routes light through an internal vacuum chamber instead of solid glass, cutting signal latency by about 30 percent.

What is a SAFE note?

A SAFE note is an investment vehicle frequently used in early-stage financing where investor funds convert into equity shares during a future priced round.

Why are data centers spreading across wider geographic areas?

Developers are encountering local electrical power grid capacity limits and political constraints, requiring them to distribute computing infrastructure across multiple physical sites while maintaining synchronized network performance.
