The fibre carries light through an air channel instead of solid glass, cutting transmission delay by roughly 47-50% versus conventional fibre. The pitch: as AI data centres spread across multiple sites due to power constraints rather than chip shortages, the speed-of-light delay between distant buildings becomes a real bottleneck. The company produced its densest cable yet with Prysmian and tested deployment with Dura-Line, positioning the tech as validated beyond lab demos. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How much faster is hollow-core fiber compared to standard fiber optic cable for data centers? Hollow-core fiber carries light roughly 47-50% faster than conventional solid-glass fiber, according to Relativity Networks and TechCrunch respectively. A signal takes about five microseconds to cross a kilometer in normal fiber versus about three and a half microseconds in hollow-core fiber, per the company's chief executive Jason Eichenholz. The gain comes from light traveling through an air-filled channel instead of solid glass. _Teams weighing latency-sensitive infrastructure choices can follow developments like this on daily.dev._ ### Why are AI data centers becoming distributed across multiple sites instead of staying in one location? Operators are running short of electrical power rather than computing chips, so they spread a single AI system across several sites to access enough power. This increases physical distance between GPUs, making the propagation delay of light through fiber a real cost that switches and software cannot remove, according to Relativity Networks' white paper on what it calls the 'AI Geography Era'. _Engineers tracking how power constraints reshape AI infrastructure design can follow this on daily.dev._ ## Similar posts on daily.dev -
