Why hollow-core fiber is attracting attention
Lower latency
Light travels primarily through air, reducing interaction and latency.
Lower loss potential
HCF has the potential to deliver lower attenuation over long distances.
Higher bandwidth
Wider optical bandwidth opens the door to future capacity growth.
Energy efficiency
Lower latency and loss can contribute to more efficient networks.
Future-ready networks
A promising technology for AI-driven, high-capacity and DCI deployments.
What you should know about HCF
How it works
HCF guides light through an air core surrounded by a microstructured cladding, reducing light-material interaction.
Where it can be used
From data center interconnects to long-haul links, HCF may enable new architectures and improved performance.
Deployment considerations
New materials and designs introduce unique handling, splicing and connectivity requirements.
Testing is critical
Accurate characterization ensures network performance, reliability and confidence at scale.
