Selective Deployment of Bidirectional Hollow-Core Fibers in Hybrid SMF/HCF Optical Networks
🤖 AI Summary
This study addresses the challenge of simultaneously achieving high throughput and energy efficiency in optical networks composed of a hybrid mix of standard single-mode fiber (SMF) and hollow-core fiber (HCF). To this end, the authors propose a selective link-upgrade strategy that replaces only 50% of the network links with bidirectional HCF. This approach significantly reduces deployment costs while delivering at least a 40% increase in network throughput and attaining 85% of the energy savings achievable by a full unidirectional HCF deployment. The key innovation lies in leveraging partial bidirectional HCF integration to closely approximate the energy efficiency of an all-HCF network under constrained upgrade ratios, while substantially enhancing transmission capacity. This strategy thus offers a practical and cost-effective pathway toward the evolution of high-capacity, energy-efficient optical networks.
📝 Abstract
We investigate selectively deploying bidirectional transmission in hybrid Hollow-Core Fiber (HCF) networks. Upgrading 50% of links to bidirectional HCF yields at least a 40% throughput increase compared to unidirectional SMF and captures 85% of the power consumption reduction of a full unidirectional HCF network upgrade.
