DescriptionThis book provides a detailed overview of the evolution of undersea communications systems, with emphasis on the most recent breakthroughs of optical submarine cable technologies based upon Wavelength Division Multiplexing, optical amplification, new-generation optical fibers, and high-speed digital electronics. The role played by submarine-communication systems in the development of high-speed networks and associated market demands for multiplying Internet and broadband services is also covered.Importance of This TopicThis book will fill the gap between highly specialized papers from large international conferences and broad-audience technology review updates. The book provides a full overview of the evolution in the field and conveys the dimension of the large undersea projects. In addition, the book uncovers the myths surrounding marine operations and installations in that domain, which have remained known so far to only very few specialists.

This publication is dirceted towards all who deal with design, construction and maintenance of fiber optic cable plants. Furthermore, it provides basic information as an introduction to specialized technical literature. In order to make it easier to study the many specialized publications, this book contains a detailed glossary of technical terms. Technical data have been updated in this new edition and sections on LAN and Fiber-in-the-Loop have been added.

There are many things and services in our everyday life that we take for granted, and telecommunications is one of them. We surf the internet, send emails to friends and colleagues abroad, talk to family members in foreign countries over the phone, book airline seats and make banking transactions without actually realizing and appreciating the sophisticated technology that enables us to do so. This report covers the history and nature of cables, their special status in international law, their interaction with the environment and other ocean users and, finally, the challenges of the future. It is an evidence-based synopsis that aims to improve the quality and availability of information to enhance understanding and cooperation between all stakeholders. UNEP-WCMC in collaboration with the International Cable Protection Committee and UNEP has prepared this new report to provide an objective, factual description of the sub-marine cable industry and the interaction of submarine telecommunications (which route 95% of all international communications traffic) with the marine environment. This important report seeks to focus and guide deliberations and decision making on the wise conservation and protection of the oceans in concert with their sustainable management and use.

The demand for high-performance submarine power cables is increasing as more and more offshore wind parks are installed, and the national electric grids are interconnected. Submarine power cables are installed for the highest voltages and power to transport electric energy under the sea between islands, countries and even continents. The installation and operation of submarine power cables is much different from land cables. Still, in most textbooks on electrical power systems, information on submarine cables is scarce. This book is closing the gap. Different species of submarine power cables and their application are explained. Students and electric engineers learn on the electric and mechanic properties of submarine cables. Project developers and utility managers will gain useful information on the necessary marine activities such as pre-laying survey, cable lay vessels, guard boats etc., for the submarine cable installation and repair. Investors and decision makers will find an overview on environmental aspects of submarine power cables. A comprehensive reference list is given for those who want further reading.

In our "wireless" world it is easy to take the importance of the undersea cable systems for granted, but the stakes of their successful operation are huge, as they are responsible for carrying almost all transoceanic Internet traffic. In The Undersea Network Nicole Starosielski follows these cables from the ocean depths to their landing zones on the sandy beaches of the South Pacific, bringing them to the surface of media scholarship and making visible the materiality of the wired network. In doing so, she charts the cable network's cultural, historical, geographic and environmental dimensions. Starosielski argues that the environments the cables occupy are historical and political realms, where the network and the connections it enables are made possible by the deliberate negotiation and manipulation of technology, culture, politics and geography. Accompanying the book is an interactive digital mapping project, where readers can trace cable routes, view photographs and archival materials, and read stories about the island cable hubs.

In Sustainable Ocean Resource Governance an international group of eminent authors offer perspectives on the legal interface between sustainable economic growth, effective marine resource management and urgent environmental protection of the sea by addressing three key issues: deep sea mining, marine energy generation, and seabed pipeline and cable systems. In light of the sectoral nature of current ocean governance and the existing patchwork of management arrangements for the oceans, this book gives insights in search for a coherent and consistent sustainability approach.

A guide to the physics of Dynamic Temperature Sensing (DTS) measurements including practical information about procedures and applications Distributed Fiber Sensing and Dynamic Ratings of Power Cable offers a comprehensive review of the physics of dynamic temperature sensing measurements (DTS), examines its functioning, and explores possible applications. The expert authors describe the available fiber optic cables, their construction, and methods of installation. The book also includes a discussion on the variety of testing methods with information on the advantages and disadvantages of each. The book reviews the application of the DTS systems in a utility environment, and highlights the possible placement of the fiber optic cable. The authors offer a detailed explanation of the cable ampacity (current rating) calculations and examines how the measured fiber temperature is used to obtain the dynamic cable rating information in real time. In addition, the book details the leading RTTR suppliers, including the verification methods they used before their products come to market. Information on future applications of the DTS technology in other aspects of power system operation is also discussed. This important book: • Explains the required calibration procedures and utility performance tests needed after the installation of a DTS system • Includes information on the various practical aspects of communicating measured and computed quantities to the transmission system operator • Reviews possible applications of the technology to fault location, vibration monitoring, and general surveying of land and submarine cable routes Written for cable engineers and manufacturers, Distributed Fiber Sensing and Dynamic Ratings of Power Cable is an authoritative guide to the physics of DTS measurements and contains information about costs, installation procedures, maintenance, and various applications.

Within the past few decades, information technologies have been evolving at a tremendous rate, causing profound changes to our world and our ways of life. In particular, fiber optics has been playing an increasingly crucial role within the telecommunication revolution. Not only most long-distance links are fiber based, but optical fibers are increasingly approaching the individual end users, providing wide bandwidth links to support all kinds of data-intensive applications such as video, voice, and data services. As an engineering discipline, fiber optics is both fascinating and challenging. Fiber optics is an area that incorporates elements from a wide range of techno- gies including optics, microelectronics, quantum electronics, semiconductors, and networking. As a result of rapid changes in almost all of these areas, fiber optics is a fast evolving field. Therefore, the need for up-to-date texts that address this growing field from an interdisciplinary perspective persists. This book presents an overview of fiber optics from a practical, engineering perspective. Therefore, in addition to topics such as lasers, detectors, and optical fibers, several topics related to electronic circuits that generate, detect, and process the optical signals are covered. In other words, this book attempts to present fiber optics not so much in terms of a field of “optics” but more from the perspective of an engineering field within “optoelectronics.
