“…and SBI refers to the interface from the relevant entity towards devices or surrogate systems. Interoperability events [233] show a high level of compliance across vendors, covering operations such as device discovery, optical channel configuration and cross-connection management.

The Covid-19 pandemic showed forcefully the fundamental importance broadband data communication and the internet has in our society. Optical communications forms the undisputable backbone of this critical infrastructure, and it is supported by an interdisciplinary research community striving to improve and develop it further. Since the first ‘Roadmap of optical communications’ was published in 2016, the field has seen significant progress in all areas, and time is ripe for an update of the research status. The optical communications area has become increasingly diverse, covering research in fundamental physics and materials science, high-speed electronics and photonics, signal processing and coding, and communication systems and networks. This roadmap describes state-of-the-art and future outlooks in the optical communications field. The article is divided into 20 sections on selected areas, each written by a leading expert in that area. The sections are thematically grouped into four parts with 4–6 sections each, covering, respectively, hardware, algorithms, networks and systems. Each section describes the current status, the future challenges, and development needed to meet said challenges in their area. As a whole, this roadmap provides a comprehensive and unprecedented overview of the contemporary optical communications research, and should be essential reading for researchers at any level active in this field.

“…Consequently, a question recently arose related on how to extract and provide GNPy inputs from a running SDN system [25]. The Telecom Infra Project (TIP) Open Optical and Packet Transport Project Group has announced the successful demonstration of open optical networks control and management by the Converged Architectures for Network Disaggregation & Integration (CANDI) [26]. After successful initial proof-of-concepts, different initiatives are currently a work in progress in this regard.…”

This tutorial considers the evolution of software-defined networking (SDN) control for optical transport networks (OTNs) in disaggregated scenarios, focusing on its requirements and challenges when applied to “beyond 100G” networks, a term that jointly refers to the use of coherent technology, data rates beyond 100G, and the evolution of OTN standards to support rates such as 200G, 400G, or 800G. The tutorial covers use-case-driven SDN development, new challenges, and requirements, such as the need to account for physical impairments, multiband/space-division multiplexing control, improved fault/alarm management, and optical telemetry and streaming. Finally, the tutorial provides an overview of new trends such as network sharing.
