Leveraging Digital Twins for All-Photonics Networks-as-a-Service: Enabling Innovation and Efficiency (Tutorial)

This tutorial presents an architecture and methods for all-photonics networks-as-a-service in distributed AI data center infrastructures. We discuss server-based coherent transceiver architectures, remote transponder control, rapid end-to-end lightpath provisioning, digital longitudinal monitoring, and line-system calibration, demonstrating their feasibility through field validations. ©2025 The Author(s)
