Cable is now as much in the broadband business as it is television. This book explains the fundamentals of coaxial cable technology and the DSP that controls it, along with the cable modem and voice over IP technology now drastically changing the cable operators’ business. Aimed at working engineers and technicians, it can also be used a textbook for the a basic cable communications course in a 2 year tech program.
The technology of undersea communications, from stranded-wire telegraph cables in the 1850s to fiber-optic cables at the end of the twentieth century, and its social, political, and economic impact. By the end of the twentieth century, fiber-optic technology had made possible a worldwide communications system of breathtaking speed and capacity. This amazing network is the latest evolution of communications technologies that began with undersea telegraph cables in the 1850s and continued with coaxial telephone cables a hundred years later. Communications under the Seas traces the development of these technologies and assesses their social, economic, and political effects. If we cannot predict the ultimate consequences of today's wired world--its impact on economic markets, free expression, and war and peace--or the outcome of the conflict between wired and wireless technology, we can examine how similar issues have been dealt with in the past. The expert contributors to this volume do just that, discussing technical developments in undersea cables (and the development of competing radio and satellite communications technology), management of the cables by private and public interests, and the impact on military and political activities. Chapters cover such topics as the daring group of nineteenth-century entrepreneurs who wove a network of copper wires around the world (and then turned conservative with success); the opening of the telegraphic network to general public use; the government- and industry-forced merger of wireless and cable companies in Britain; and the impact of the cable network on diplomacy during the two world wars.
Fully updated, revised, and expanded, this second edition of Modern Cable Television Technology addresses the significant changes undergone by cable since 1999--including, most notably, its continued transformation from a system for delivery of television to a scalable-bandwidth platform for a broad range of communication services. It provides in-depth coverage of high speed data transmission, home networking, IP-based voice, optical dense wavelength division multiplexing, new video compression techniques, integrated voice/video/data transport, and much more. Intended as a day-to-day reference for cable engineers, this book illuminates all the technologies involved in building and maintaining a cable system. But it's also a great study guide for candidates for SCTE certification, and its careful explanations will benefit any technician whose work involves connecting to a cable system or building products that consume cable services. - Written by four of the most highly-esteemed cable engineers in the industry with a wealth of experience in cable, consumer electronics, and telecommunications - All new material on digital technologies, new practices for delivering high speed data, home networking, IP-based voice technology, optical dense wavelength division multiplexing (DWDM), new video compression techniques, and integrated voice/video/data transport - Covers the latest on emerging digital standards for voice, data, video, and multimedia - Presents distribution systems, from drops through fiber optics, an covers everything from basic principles to network architectures
This book explains the functions and operation of cable television (CATV) systems, TV technologies including MPEG, DOCSIS cable modems, and distribution systems. It covers CATV services including advertising, tCommerce, home networking with DLNA, and how it is combining with Internet TV using HbbTV.
This practical, detailed book is the most complete and comprehensive guide to structured cable systems. It presents the fundamentals of electric and fibre optic cables as well as all the practical aspects, combined with additional reference information on technical data and terms in an appendix.
Power Cable Technology provides a precise understanding of the design, manufacture, installation, and testing of a range of electric power cables—from low-voltage, 1,000/1,100V cables to extra-high-voltage, 400kV cables—with reference to future trends in the industry. The authors’ mantra is: know your cable. Thus, the book begins with a comprehensive overview of power cable design and manufacturing through the ages, and then: Describes the characteristics of the materials currently used in the production of various power cables Explains how to calculate the die orifice for drawing wires, how tolerance in manufacturing affects material weight and consumption, and how and why lubricants are used Addresses the formation, stranding, and insulation of the electrical conductors, as well as the sheathing, armouring, and protective covering of the power cables Delivers an in-depth discussion of quality systems, quality control, and performance testing Covers the many nuances of cable installation, including laying, jointing, and terminating Throughout, the authors emphasise consonance between design theory and practical application to ensure production of a quality power cable at a reasonable cost. They also underscore the importance of careful handling, making Power Cable Technology a must read for power cable engineers and technicians alike.
This book will discuss the principles of operation and features for the emerging consumer home terminals such as digital set-top boxes and cable modems. This book will also provide the detailed technical principles of both fiber optics and RF cable TV systems.
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.
The industrial nations of the world have become Information Societies. Advanced technologies have created a communication revolution, and the individual, through the advent of computers, has become an active participant in this process. The "human" aspect, therefore, is as important as technologically advanced media systems in understanding communication technology. The flagship book in the Series in Communication Technology & Society, Communication Technology introduces the history and uses of the new technologies and examines basic issues posed by interactive media in areas that affect intellectual, organization, and social life. Author and series co-editor Everett M. Rogers defines the field of communication technology with its major implications for researchers, students, and practitioners in an age of ever more advanced information exchange.
Communication Technology Update, Third Edition provides the latest information on as many communication technologies as possible, using as many specific statistics on market share, units sold, etc., as possible to allow comparison among the technologies. This book is designed to help make sense of the spectrum of communication technologies. The text explores the widest possible range of technologies, from broadcast to telephony and from wired to wireless. In discussing each technology, this book will not only deal with the hardware of the technology, but also with the software, organizational structure, political and economic influences, and individual users of the technologies. Major developments in each of these areas are presented for each technology, along with background information to help explain the major factors in the evolution of the technology. The first chapter begins by defining communication technology and introducing the ""umbrella perspective"" used to present and analyze each technology. Following this discussion, an overview of the remainder of the book is presented. This book targets two groups of users. One of which is the group of communication professionals who have a desire to keep up with the latest developments both within and adjacent to their particular fields. Second is the group of students who are studying communication technology and need information that is more current than that provided by a textbook and more comprehensive than that found in trade magazines.
