Selective Deployment of Bidirectional Hollow-Core Fibers in Hybrid SMF/HCF Optical Networks

Mëmëdhe Ibrahimi, Giovanni S. Sticca, Angelo Ferrara, Massimo Tornatore

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.

Transition-Aware Routing in Hybrid Hollow-Core/Single-Mode Fiber Networks: A Cost--Throughput Investigation

Md Ghulam Saber, Zhiping Jiang

Incremental deployment of hollow-core fiber (HCF) in single-mode-fiber (SMF) networks introduces a routing tradeoff: reducing HCF-SMF transitions can improve physical-layer feasibility, but overly transition-averse routing incurs harmful path detours. We study this tradeoff using…

LLMs and Optical Networks: A Symbiotic Relationship

Mëmëdhe Ibrahimi, Qiaolun Zhang, Giovanni S. Sticca, Jiaheng Xiong, Francesco Musumeci, Massimo Tornatore

This paper explores the emerging symbiosis between LLMs and optical networks. Massive LLMs require geo-distributed training, which demands advanced optical transport capabilities that require new key technical enablers, as WAN-aware CCL algorithms, ZR+ pluggables, and Hollow Core…
