Relativity raises $22M for faster AI fiber

Relativity Networks raised $22 million and secured a $40 million follow-on order from an unnamed hyperscaler for hollow-core fiber, which the company says cuts signal travel from roughly 5 to 3.5 microseconds per kilometer. TechCrunch’s report describes the technology as a way to join geographically separated data-center campuses without treating distance as a fixed networking tax. Builders tracking AI power and infrastructure contracts should file the premise, while remembering that the order is not proof of broad deployment economics.
