Lo, soul! seest thou not God's purpose from the first? The earth to be spann'd, connected by net-work From Passage to India! Walt Whitman, "Leaves of Grass", 1900. The Internet is growing at a tremendous rate today. New services, such as telephony and multimedia, are being added to the pure data-delivery framework of yesterday. Such high demands on capacity could lead to a "bandwidth-crunch" at the core wide-area network resulting in degra dation of service quality. Fortunately, technological innovations have emerged which can provide relief to the end-user to overcome the In ternet's well-known delay and bandwidth limitations. At the physical layer, a major overhaul of existing networks has been envisaged from electronic media (such as twisted-pair and cable) to optical fibers - in the wide area, in the metropolitan area, and even in the local area set tings. In order to exploit the immense bandwidth potential of the optical fiber, interesting multiplexing techniques have been developed over the years. Wavelength division multiplexing (WDM) is such a promising tech nique in which multiple channels are operated along a single fiber si multaneously, each on a different wavelength. These channels can be independently modulated to accommodate dissimilar bit rates and data formats, if so desired. Thus, WDM carves up the huge bandwidth of an optical fiber into channels whose bandwidths (1-10 Gbps) are compati ble with peak electronic processing speed.

Optical WDM networking technology is spearheading a bandwidth revolution in the networking infrastructure being developed for the next generation Internet. Rapid advances in optical components have enabled the transition from point-to-point WDM links to all-optical networking. Optical WDM Networks: Principles and Practice presents some of the most important challenges facing the optical networking community, along with some suggested solutions. Earlier textbooks in optical networking have a narrower perspective, and rapidly advancing research has created the need for fresh and current information on problems and issues in the field. The volume editors and contributing authors have endeavoured to capture a substantial subset of the key problems and known solutions to these problems. All of the chapters are original contributions from leading international researchers. The chapters address a wide variety of topics, including the state of the art in WDM technology, physical components that make up WDM fiber-optic networks, medium access protocols, wavelength routed networks, optical access networks, network management, and performance evaluation of wavelength routing networks. The chapters also survey critical points in past research and tackle more recent problems. Practitioners and network product engineers interested in current state-of-the-art information beyond textbook-type coverage, and graduate students commencing research in this area, will appreciate the concise - and pertinent - information presented herein.

Optical communications networks are an essential part of the world wide te- communication infrastructure . The number of users of present and future telecommunication services like Internet, web browsing and tele-education is expected to increase dramatically . As a consequence there is an imminent - mand for high broadband and high capacity communication systems. A prom- ing solution is found in the concept of all-optical networks . These networks exploit the vast capacity of the optical fiber by using multiplexing techniques that allow for an overall capacity of terabits per second. Channels are routed and switched in the optical domain . In this manner data channels are carried from the receiver side to its destination making use of optical transmission techniques . Wavelength division multiplexing (WDM) is a transmission technique that has dramatically increased the capacity of optical transmission systems. WDM allows for transmission of several channels over a single optical fiber by - ing different wavelength as the channel carrier . Optical switching and routing techniques are also being developed to cope with the high data speeds and n- ber of channel carried in the optical fibers. These functionalities are provided by optical crossconnects. The use of transmission techniques such as WDM in combination with optical crossconnects is enabling optical networking at high bit-rates reaching terabits per second . These techniques also offer ways to improve the network flexibility and configurability .

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.
