Prysmian and Relativity Networks partner to deploy highest-density hollow-core fiber cable

Type: Partnership · Technology: Telecom · Country: United States · Announced: 2026-07-24

Prysmian and Relativity Networks announced a partnership to deploy their highest-density hollow-core fiber cable in July 2026. The cable, built on Prysmian's Sirocco architecture and incorporating Relativity Networks' ChronoCore fibers, was tested at Dura-Line's facility in Clinton, Tennessee at jetting speeds of up to 350 ft/min. The deployment demonstrates the technology's readiness for real‑world use, extending fiber reach from 60 km to 90 km while delivering lower latency for data center networks. This milestone supports the growing demand from hyperscale AI data center operators for next‑generation low‑latency infrastructure. The collaboration highlights both companies' leadership in digital infrastructure innovation.
