Data center interconnections require speed, resiliency, and superior fiber-optic performance. Emerging technologies such as hollow-core fiber (HCF) deliver significant benefits, like ultra-low latency, but also introduce new challenges for installation and testing. In this tech showcase, VIAVI shares best practices for testing hollow-core fiber, highlighting HCF’s technical advantages and key applications in AI, quantum communications, and Cloud infrastructure. In particular we address:

  • Overcoming installation challenges specific to hollow-core fiber
  • Efficient HCF testing using enhanced Optical Time Domain Reflectometer (OTDR) performance
  • Dispersion testing and the importance of understanding the attenuation profile
  • Guaranteeing long-term performance, reliability, and compliance for critical links
