Explaining what CWDM is, how it is achieved, and why it should be deployed, Coarse Wavelength Division Multiplexing: Technologies and Applications merges coverage of isolated aspects of Coarse Wavelength Division Multiplexing (CWDM) traditionally found as device-related or specific system topics. Emphasizing cost savings and performance enhancement, the book integrates information on component issues, system architectures, concepts for extensions and upgrades, as well as practical applications into a comprehensive, single-volume resource. Beginning with a summary of the ITU-T standards defining CWDM, the book addresses the three essential component classes, optical fibers, transceivers, and WDM filters, which combine to form the basis for the CWDM transmission link. The following chapters include coverage of different architectures such as hubbed rings and meshed networks, and upgrade paths to overcome limitations of current CWDM systems. The book outlines the feasibility of optically amplified CWDM systems, investigates the challenges present with high-speed CWDM and bidirectional transmission, and finally elucidates the importance of CWDM for a wide range of applications. Each chapter provides sufficient information to be used independently and contains references to relevant papers and articles for further study. The last sections of the book focus on applications and case studies where CWDM plays an ever-increasing role. They include extensive studies on networking, reach extension by amplification, and the latest concepts of transmission capacity upgrades using increased bit-rates or new channel plans. Filled with practical information, the book provides a clear understanding of recent developments in the dynamic field of CWDM.

This book focuses on methods for service-differentiated and constraint-based wavelength routing and resource allocation for multi-service WDM networks. A number of unique routing solutions are proposed, and an extensive analysis of dynamically re-configurable multi-service WDM networks impart the major contribution to the current efforts in standardisation and network operation.

The optically pumped laser has made an enormous contribution to research in the part of the electromagnetic spectrum known as the far infrared, or submillimetre region. I hope that this book will be useful to both practising and prospective workers in the field, since it contains an up-to-date catalogue of measurements of the main properties of submillimetre lasers as well as an introductory review of the measurement techniques themselves. Wavelength and frequency measurements have been exhaustively compiled (in Part II of this book) along with molecule and pump identification. Part I contains a short review of the relevant measurement techniques in each of these areas and, in addition, a review of power measurements. Working in this field, as in any other, one's satisfaction is determined largely by the colleagues one has and the friends one makes along the way. I am very grateful to Dr G. Dodel, Dr L. C. Robinson and Dr G. F. Brand for introducing me to the field. Dr I. S. Falconer and Dr P. A. Krug have been good colleagues and friends. For this book in particular I am grateful to Dr Dodel, Dr K. M. Evenson, Dr H. Figger, Prof. M. Fourrier, P. Kempf, Dr K. J. Siemsen and Dr M. S. Tobin for their comments, and to Dr D. J. E. Knight for a great deal of help, including data from unpublished or obscure sources which he had gathered for his own compilation.

In this book, Optical Wavelength Division Multiplexing (WDM) is approached from a strictly practical and application-oriented point of view. Based on the characteristics and constraints of modern fiber-optic components, transport systems and fibers, the text provides relevant rules of thumb and practical hints for technology selection, WDM system and link dimensioning, and also for network-related aspects such as wavelength assignment and resilience mechanisms. Actual 10/40 Gb/s WDM systems are considered, and a preview of the upcoming 100 Gb/s systems and technologies for even higher bit rates is given as well. Key features: Considers WDM from ULH backbone (big picture view) down to PON access (micro view). Includes all major telecom and datacom applications. Provides the relevant background for state-of-the-art and next-gen systems. Offers practical guidelines for system / link engineering.

An all-encompassing view of the life and work of one of Canada’s greatest living artists Michael Snow is rightly recognized as one of the greatest Canadian artists. In a productive, lengthy career, he has, in a wide variety of genres and media, asked (and often answered) some of the most vexing and important questions in the history of art. During his lifetime, the notion of what constitutes a work of art has undergone many changes, and his work has consistently been at the forefront of that discussion. Michael Snow: Lives and Works examines all aspects of the artist’s work and provides a guide to understanding its subtleties and complexities. The book also charts the life of Snow: his early years as a student and artist in Toronto, his stay in New York City, his turbulent marriage to Joyce Wieland, his reputation as a lady’s man, and his adventures in movie making and improvised music. In many ways, Snow is the visual artist as intellectual: his images are vibrant and compelling, but so are the ideas behind them. Ultimately, his work is about perception. What do we really see when we look at a work of art? What is the act of looking all about? What exactly is a work of art? Michael Snow: Lives and Works is a personal and intimate portrait of an artist who has helped shaped the face of Canadian art in our time.
