LLMs and Optical Networks: A Symbiotic Relationship
Mëmëdhe Ibrahimi, Qiaolun Zhang, Giovanni S. Sticca +3
This paper explores the emerging symbiosis between LLMs and optical networks. Massive LLMs require geo-distributed training, which demands advanced optical transport capabilities t…
Selective Deployment of Bidirectional Hollow-Core Fibers in Hybrid SMF/HCF Optical Networks
Mëmëdhe Ibrahimi, Giovanni S. Sticca, Angelo Ferrara +1
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% throug…
Selective Placement of Hollow-Core Fibers for QKD and Classical Communication Coexistence
Giovanni Simone Sticca, Alessandro Gagliano, Memedhe Ibrahimi +3
We investigate the benefits of partially upgrading optical networks with hollow-core fibers for QKD-classical communication coexistence. Results show that upgrading 40% of links in…
Vertical Federated Learning for Failure-Cause Identification in Disaggregated Microwave Networks
Fatih Temiz, Memedhe Ibrahimi, Francesco Musumeci +2
Machine Learning (ML) has proven to be a promising solution to provide novel scalable and efficient fault management solutions in modern 5G-and-beyond communication networks. In th…
Multi-Failure Localization in High-Degree ROADM-based Optical Networks using Rules-Informed Neural Networks
Ruikun Wang, Qiaolun Zhang, Jiawei Zhang +7
To accommodate ever-growing traffic, network operators are actively deploying high-degree reconfigurable optical add/drop multiplexers (ROADMs) to build large-capacity optical netw…
