Eindhoven accelerates the future with Hollow Core Fiber (HCF)
The rise of artificial intelligence is driving an unprecedented growth in data traffic worldwide. As AI applications and data centers continue to expand, faster and more reliable connectivity is becoming increasingly important. Hollow Core Fiber is one of the technologies helping to meet these demands and support the next generation of digital infrastructure.
Prysmian, together with Relativity Networks and Dura-Line, has reached an important milestone in the development of Hollow Core Fiber (HCF). Recent deployment tests successfully demonstrated the reliable installation of a high-density cable incorporating Relativity Networks' ChronoCore™ hollow core fibers, confirming the solution's readiness for real-world AI and data center applications.
The cable combines Prysmian's expertise in high-density cable design and manufacturing with Relativity Networks' breakthrough hollow core fiber technology. The result is an innovative solution designed to support next-generation low-latency digital infrastructure, where high-speed data transmission is increasingly critical.
For the Netherlands, this milestone is particularly significant. Prysmian is actively scaling up the production of hollow core fiber, with the Eindhoven facility playing a key role in the industrialization of this technology. The site is helping to advance the manufacturing processes, expertise and capabilities needed to bring hollow core fiber technology to market at scale.
What makes Hollow Core Fiber unique is the way it transmits light. Unlike conventional optical fiber, where light travels through glass, hollow core fiber guides light through an air-filled core. Because light travels faster in air than in glass, hollow core fiber can transmit data nearly 50% faster than traditional communications fiber, significantly reducing latency for time-critical applications.
One promising use case is data center interconnectivity. As AI workloads continue to grow, data centers require ever-faster communication between locations. Hollow Core Fiber can help extend the distance between synchronized data centers, providing operators with greater flexibility when selecting sites while supporting the rapidly expanding demands of AI infrastructure.
By continuing to invest in innovation, manufacturing capability and technical expertise, Prysmian is helping shape the digital infrastructure of tomorrow. The work being carried out in Eindhoven demonstrates how local innovation can contribute to global technological progress and support the accelerating demands of the AI era.
