Hollow Core Fiber: Powering the Next Generation of Data Centers
The rapid growth of artificial intelligence, cloud computing, and hyperscale architectures is driving new connectivity requirements across data center networks. Operators need infrastructure that delivers lower latency, higher performance, and improved energy efficiency.
Prysmian's Hollow Core Fiber (HCF) represents a breakthrough in optical networking. By guiding light through an air-filled core instead of solid glass, HCF enables data transmission rates that are up to nearly 50% faster than conventional optical fiber while significantly reducing latency.
These unique characteristics make HCF ideally suited for:
- AI and GPU clusters,
- Data Center Interconnect (DCI),
- High-performance cloud infrastructures,
- Low-latency financial networks,
- HPC and advanced computing environments.
With transmission distances of up to 90 km without compromising latency, HCF offers greater flexibility in data center location strategies and supports more energy-efficient infrastructure deployment.
Fully compatible with existing network infrastructures, Hollow Core Fiber provides a seamless migration path while preparing organizations for the future demands of AI workloads, machine learning, and large-scale data processing.

Hollow Core Fiber: Accelerating the Next Generation of Data Centers
The rise of artificial intelligence, cloud computing, and hyperscale architectures is driving new demands for connectivity. Data center operators are now looking for infrastructure capable of reducing latency, increasing throughput, and improving energy efficiency.
Prysmian's Hollow Core Fiber (HCF) technology represents a major breakthrough for critical networks. By guiding light through an air core rather than through glass, it enables data transmission that is up to nearly 50% faster than conventional optical fiber while significantly reducing latency.
This performance helps optimize applications that are most sensitive to response time, such as:
- AI and GPU clusters,
- data center interconnects (DCI),
- high-performance cloud environments,
- low-latency financial infrastructure,
- HPC and high-performance computing networks.
The extended range of HCF technology also allows for coverage of up to 90 km without a significant impact on latency, providing greater flexibility in infrastructure deployment and promoting better energy optimization at sites.
Compatible with existing architectures, Hollow Core Fiber facilitates a phased adoption while preparing networks for the future needs of AI applications, machine learning, and massive data exchanges.
