Relativity Networks Raises $10.7 Million to Meet Data Center Demand for Hollow-Core Fiber Cable

Relativity Networks has received $10.7 million in investments to produce and deliver more hollow-core fiber (HCF) cables for data centers requiring large amounts of energy as AI adoption increases. Among the investors are Prysmian, GOVO Venture Partners, and a “group of new and previous investors who invested in Relativity’s pre-seed round” per PR Newswire.

Relativity Networks had agreed to a long-term partnership with Prysmian in March, leading to HCF cables already being delivered to hyperscalers who want to utilize the cables in their data centers at scale.

"This investment represents a pivotal milestone in Relativity Networks' mission to address two of the most urgent infrastructure challenges of the AI revolution – latency and access to power," said Relativity Networks founder and CEO Jason Eichenholz. "As data centers face unprecedented energy demands and latency requirements, our hollow-core fiber technology delivers the critical infrastructure backbone needed to support this exponential growth. This funding – along with our continued partnership with Prysmian – allows us to accelerate our ability to meet the surging demand for infrastructure that can handle AI's massive computational requirements." 

The company’s HCF can transmit data almost 50% faster than standard silica glass fiber and increases the distance between power suppliers and data centers to 56 miles, versus the standard 37 miles.
