Submarine fiber optic cables are critical communications infrastructure for States around the world. They are laid on the seabed, are often no bigger than a garden hose, and transmit immense amounts of data across oceans. These cables are the backbone of the internet and phone services and underpin core State interests, such as the finance sector, shipping, commerce and banking industries. Without the capacity to transmit and receive data via submarine cables, the economic security of States would be severely compromised. Despite the fact that 95 per cent of all data and telecommunications between States are transmitted via submarine cables, there is little understanding of how these cables operate. As a result some States have developed policies and laws that undermine the integrity of international telecommunications systems. Submarine Cables: The Handbook of Law and Policy provides a one-stop-shop of essential information relating to the international governance of submarine cables. The Handbook is a unique collaboration between international lawyers and experts from the submarine cable industry. It provides a practical insight into the law and policy issues that affect the protection of submarine cables, as well as the laying, maintenance and operation of such cables. In addition, the law and policy issues in relation to other special purpose cables, such as power cables, marine scientific research cables, military cables, and offshore energy cables, are also addressed.
This book highlights the critical importance of laying, quick relinking, and protecting submarine cables with timely approval for carriers and cable repairing ships and how these are most challenging in many jurisdictions. It identifies that a dedicated national instrument on submarine cable as a way forward is yet to be appreciated by many States, and presently, there is no model legal framework for national instruments on submarine cables available. To bridge these gaps, the book undertakes a systematic inquiry and analysis of submarine cable regimes' and relevant authorities. It consults existing knowledge on international law on cables and analyzes specific principles and provisions on laying repair and maintenance of submarine cables and states’ obligations towards protecting cables from vulnerabilities. It touches upon cable regulation in the deep sea concerning the International Seabed Authority and proposed biodiversity agreement. It indicates suitable measures on cable laying, etc., and security risks in the marine space beyond the national jurisdictions. To map States’ response, it explores the domestic cable regimes, including both the selected jurisdictions and Australia and New Zealand, analyses specific legal provisions and institutional set-up, and demonstrates state practices, approaches, and loopholes in the governance of the cable system within national jurisdictions. The book suggests adopting the spatial ocean management approach, dedicated regulatory authority, a competent enforcement agency, strict liability with exemplary punishment on cable damage, and the cable system to strengthen the cable system's management. Finally, it arranges the fundamental premises of a common minimum framework for national instruments seeking coastal states’ deliberations in implementing initiatives towards a robust law and policy for reliability, resiliency, and security of the cable system. The cable industries, pipeline, fishing, shipping industries, academicians, government authorities, international bodies, and the maritime community worldwide are looking at the issues and challenges of submarine cable regimes, particularly national regimes and suggestive remedial measures. These stakeholders will find the book a useful reference.

Electric Cables Handbook is an extensive source of up-to-date and essential information for electrical engineers, contractors, supply authorities and cable manufacturers.
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.
Excerpt from Handbook of Submarine Cables: U. S. Signal Corps Prior to 1898 the duties of installing and operating submarine cables devolved but rarely on the Signal Corps of the Army, and in such cases only along the coasts of the United States where technical labor and special material were readily available. The war of 1898 necessitated on the part of the Signal Corps extensive cable operations in the Carribean Sea and in the Philippine Archipelago, while later They have been extended to Alaskan waters. Under such conditions it was impracticable to either lay such cables by contract or to operate them by civilian force. In consequence, it devolved upon the Chief Signal Officer of the Army, Gen. A. W. Greely, to organize a system under which the installation, operation, and maintenance of long submarine cables should be efficiently performed by the officers and men of the Signal Corps of the Army. The situation was further complicated by the fact that up to that date no long submarine cable of American manufacture had ever been successfully installed and operated. In 1902 it became necessary to issue a handbook, setting forth the means and methods utilized in cable operations by the Signal Corps of the Army. In preparing this manual Major Russel has utilized such extracts from the books of reference named and such Signal Corps reports and drawings as have seemed of general interest. As the handbook was intended for a practical guide to officers of the Signal Corps, particular value was attached to the extended experiences of signal corps officers in installing and operating submarine cables. Such cable operations involving miles of cables have been conducted by the Signal Corps under varying physical conditions, from the icy waters of Bering Strait to the tropical sea of Sulu. Jolo Archipelago. As a rule complicated formulae or theoretical considerations have been avoided in this manual. Simplicity has been sought in describing the various tests, so that the methods followed may be readily comprehended and successfully applied. All the tests referred to have been in actual use at signal corps stations or on the cableship Burnside. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
