This book is not only thorough in covering the physics and the applications of optical communications, but it discusses the relevance of technology to the emerging intelligent optical networking revolution. This should be mandatory reading for every professional in our business. Desh Deshpande, Chairman, Sycamore Networks, Inc.This edition of Optical Networks will greatly aid everyone in the business of creating change and help them understand the science behind and the applications of an optical world. Mike Perusse, Senior Vice President of Engineering and Technology, QwestRajiv Ramaswami is the industry's best teacher on optical technology, and this book is the most lucid, scholarly, and enlightening guide to wavelength division multiplexing published to date. George Gilder, Editor, Gilder Technology Report and author of TelecosmThis fully updated and expanded second edition of Optical Networks: A Practical Perspective succeeds the first as the authoritative source for information on optical networking technologies and techniques. Written by two of the field's most respected individuals, it covers componentry and transmission in detail but also emphasizes the practical networking issues that affect organizations as they evaluate, deploy, or develop optical solutions.This book captures all the hard-to-find information on architecture, control and management, and other communications topics that will affect you every step of the way-from planning to decision-making to implementation to ongoing maintenance. If your goal is to thoroughly understandpractical optical networks, this book should be your first and foremost resource.FeaturesFocuses on practical, networking-specific issues: everything you need to know to implement currently available optical solutions.Provides the transmission and component details you need to understand and assess competing technologies.Offers updated and expanded coverage of propagation, lasers and optical switching technology, network design, transmission design, IP over WDM, wavelength routing, optical standards, and more.

Networking books come in two basic flavors: Platform-neutral and vendor-specific. Nortel Networks: The Complete Reference takes mainly the latter approach, explaining how data moves across (and among) networks based on Nortel equipment, including those products Nortel acquired when it bought Bay Networks. There''s rather a lot of theory and quite a number of universal truths mixed in with the Nortel information. For that reason, and because author James Knapp''s presentation style is so strong, you''re likely to derive value from this work even if you use other companies'' hardware and software. Knapp''s coverage runs the gamut from local Ethernet to Layer 3 switching, Asynchronous Transfer Mode (ATM), and internetworking, so there''s something here for network engineers in organizations large and small. Knapp''s approach is unfailingly practical, always considering real-life situations and the best way to derive maximum performance from real networks. To this end, he''s included numerous anecdotes from his time spent as a Nortel engineer, and he''s provided conceptual background with excellent diagrams in many cases. You''ll particularly love this book if you own one of the Nortel products--listed below--that Knapp thoroughly investigates. For each covered product, you get a highly detailed look at its capabilities, appropriate use, and management specifics--all in an easy-to-follow style. For a shop that uses Nortel network equipment, this book should be required documentation. --David Wall Topics covered: Theory of Ethernet and the Open Systems Interconnect (OSI) reference model, Ethernet implementations (with emphasis on BayStack, Centillion, and LattisSpan equipment), Layer 3 switching with Accelar gear, Asynchronous Transfer Mode (ATM) concepts (including Quality of Service and Private Network-to-Network Interfaces), ATM as implemented under the Centillion series, and internetwork routing with Nortel routers.
