Three sets of ocean liners, each destined to be of three vessels, dominated the Atlantic in the Edwardian era. The race to build the biggest and the best began with Mauretania and Lusitania in 1906, followed by the White Star Line's Olympic and Titanic in 1911-12. Each of these pairs was to see a larger sister, developed as a result of changes needed or desired as a result of operating the two earlier vessels, with Cunard's being Aquitania and White Star's, the ill-fated Britannic. Germany's answer to these British behemoths was the Albert-Ballin designed trio of Imperator, Vaterland and Bismarck. Through misfortune or war, two of these vessels would sink but the others led useful lives, with Aquitania surviving two world wars before being scrapped. Designed to be the absolute engineering achievements of their time, these nine vessels dominated the Atlantic. J. Kent Layton tells the story of the Edwardian Superliners in this fabulously illustrated volume, showcasing many images previously unpublished and never before seen. Rarely can one describe a book as definitive, but this volume truly deserves the accolade.

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.
