Book excerpt: The original essays in this collection ground the shifting terrain of feminism in the 21st century. The contributors define and examine the complexity of the Third Wave by answering questions like: how appropriate is a "third wave" label for contemporary feminism; are the agendas of contemporary feminism and the "second wave" really all that different; does the wave metaphor accurately describe the difference between contemporary feminists and their predecessors; how do women of color fit into this notion of contemporary feminism; and what are the future directions of the feminist movement?

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

This book was released on 2012-12-06 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical networks, employing Wavelength-Division Multiplexing (WDM) and wavelength routing, are believed to be the answer for the explosion in IP traffic and the emergence of real-time multimedia applications. These networks offer quantum leaps in transmission capacity as well as eliminate the electronic bottleneck in existing metropolitan and backbone networks. During the last decade, we witnessed a tremendous growth in the theoretical and experimental studies focusing on the cost-effective deployment of wavelength routed networks. The majority of these studies, however, assumed ideal behavior of optical devices. In this book, we argue that for the successful deployment of optical networks, design algorithms and network protocols must be extended to accommodate the non-ideal behavior of optical devices. These extensions should not only focus on maintaining acceptable signal quality (e.g., 12 maintaining BER above 10- ), but should also motivate the development of optimization algorithms and signaling protocols which take transmission impairments into consideration. In addition, the design of enabling technologies, such as optical cross-connects, should be transmission-efficient. This book is a comprehensive treatment of the impact of transmission impairments on the design and management of wavelength-routed networks. We start with transparent networks, focusing on power implications such as cross-connect design, device allocation problems, and management issues. In this all-optical model, we propose a design space based on reduction in overall cost and ease of network management. This design concept, motivates various switch architectures and different optimization problems.
