Some of the important issues involving these new technologies involve the architectural, protocol, and performance related issues. This book addresses many of these issues and presents a birds eye view of some of the more promising technologies. Researchers and those pursuing advanced degrees in this field will be able to see where progress is being made and new technologies are emerging. Emerging Optical Network Technologies: Architectures, Protocols and Performance provides state-of-the-art material written by the most prominent professionals in their respective areas.

A strategic guide to the practical business applications of optical networking technologies Optical Networking A Wiley Tech Brief Optical networks are spreading outward from Internet backbones to cities to corporations and even to the home. Cities are in a strategic position to create a leading-edge optical infrastructure that will drive economic growth. Optical technologies can cost-effectively meet corporate bandwidth needs today and tomorrow, from optical Internet connections offering bandwidth on demand to fiber on the LAN. Fiber to the home can provide true broadband connectivity for telecommuters as well as converged multimedia offerings for consumers. The ever-expanding need for bandwidth can only be met by optical networks and their phenomenal data capacity. In this book, the real-world applications driving optical networking deployments are explored. You'll get a detailed look inside the markets for fiber, bandwidth supply and demand, and optical networking technology. Both traditional architectures, such as SONET, and emerging paradigms, such as IP over DWDM and Gigabit Ethernet, are examined. This book provides practical information, insight, and case studies about the business benefits and broad range of optical networking technologies and applications available today, including: * Optical internets that run IP directly over fiber without intervening layers of ATM and SONET * Municipal optical networks and their ability to transform local economies * Corporate optical networking deployments, from LAN to WAN to Internet connections * Gigabit Ethernet and bandwidth on demand * Fiber to the home-and why pseudobroadband alternatives such as DSL and cable modems are inadequate * Why wireless is not an alternative to fiber Wiley Tech Briefs Focused on the needs of the corporate IT and business manager, the Tech Briefs series provides in-depth information on new or emerging technologies, solutions, and vendor offerings available in the marketplace. With their accessible approach, these books will help you get quickly up-to-speed on a topic so that you can effectively compete, grow, and better serve your customers.

Following the emergence of lasers and optical fibers, optical networking made its beginning in the 1970s with high-speed LANs/MANs. In the 1980s, when the bandwidth of intercity microwave links turned out to be inadequate for digital telephony, the technology for single-wavelength optical communications using SONET/SDH arrived as a saviour to replace the microwave links. However, single-wavelength links couldn't utilize the huge bandwidth (40 THz) of optical fibers, while the bandwidth demands kept soaring. This necessitated the use of wavelength-division multiplexing (WDM) for concurrent transmission over multiple wavelengths, increasing the available bandwidth significantly. Today, optical networking has become an indispensable part of telecommunication networks at all hierarchical levels. The book Optical Networks provides a graduate level presentation of optical networks, capturing the past, present and ensuing developments with a unique blend of breadth and depth. The book is organized in four parts and three appendices. Part I presents an overview and the enabling technologies in two chapters, Part II presents the single-wavelength optical networks in three chapters, while Part III deals with the various forms of WDM optical networks in four chapters. Finally, Part IV presents some selected topics in six chapters, dealing with a number of contemporary and emerging topics. Optical Networks provides a comprehensive all-in-one text for beginning graduate as well as final-year undergraduate students, and also allows R&D engineers to quickly refresh the basics and then move on to emerging topics.

By the end of the decade, approximately 50 billion devices will be connected over the internet using multiple services such as online gaming, ultra-high definition videos, and 5G mobile services. The associated data traffic demand in both fixed and mobile networks is increasing dramatically, causing network operators to have to migrate the existing optical networks towards next-generation solutions. The main challenge within this development stems from network operators having difficulties finding cost-effective next-generation optical network solutions that can match future high capacity demand in terms of data, reach, and the number of subscribers to support multiple network services on a common network infrastructure. Design, Implementation, and Analysis of Next Generation Optical Networks: Emerging Research and Opportunities is an essential reference source that discusses the next generation of high capacity passive optical access networks (PON) in terms of design, implementation, and analysis and offers a complete reference of technology solutions for next-generation optical networks. Featuring research on topics such as artificial intelligence, electromagnetic interface, and wireless communication, this book is ideally designed for researchers, engineers, scientists, and students interested in understanding, designing, and analyzing the next generation of optical networks.

A guide to light-based networks. Advantages of optical nets include greater bandwidth and speed. Covers architecture, design, and monitoring/management issues.

This book takes a pragmatic approach to deploying state-of-the-art optical networking equipment in metro-core and backbone networks. The book is oriented towards practical implementation of optical network design. Algorithms and methodologies related to routing, regeneration, wavelength assignment, sub rate-traffic grooming and protection are presented, with an emphasis on optical-bypass-enabled (or all-optical) networks. The author has emphasized the economics of optical networking, with a full chapter of economic studies that offer guidelines as to when and how optical-bypass technology should be deployed. This new edition contains: new chapter on dynamic optical networking and a new chapter on flexible/elastic optical networks. Expanded coverage of new physical-layer technology (e.g., coherent detection) and its impact on network design and enhanced coverage of ROADM architectures and properties, including colorless, directionless, contentionless and gridless. Covers ‘hot’ topics, such as Software Defined Networking and energy efficiency, algorithmic advancements and techniques, especially in the area of impairment-aware routing and wavelength assignment. Provides more illustrative examples of concepts are provided, using three reference networks (the topology files for the networks are provided on a web site, for further studies by the reader). Also exercises have been added at the end of the chapters to enhance the book’s utility as a course textbook.
