Prysmian will manufacture fibers and cables using Relativity Networks’ patent-pending hollow-core fiber (HCF) technology at a dedicated facility located in Prysmian’s production center in Eindhoven, Netherlands. In addition, Relativity Networks will provide connectors and hardware that ensure compatibility with existing fiber-optic interfaces.
The strategic production site will enable the companies to meet the growing global demand for innovative optical fiber solutions, ensuring that data centers and AI applications benefit from cutting-edge fiber-optic technology.
Hollow-core fiber transmits data nearly 50 percent faster when compared with the conventional fiber-optic cable long in use by the data industry and enables data to travel 1.5 times farther without impacting the latency that can throw intricate multi-location data operations and applications out of sync.
