With optical fiber telecommunications firmly entrenched in the global information infrastructure, a key question for the future is how deeply will optical communications penetrate and complement other forms of communication (e.g., wireless access, on-premises networks, interconnects, and satellites). _Optical Fiber Telecommunications_, the seventh edition of the classic series that has chronicled the progress in the research and development of lightwave communications since 1979, examines present and future opportunities by presenting the latest advances on key topics such as: * Fiber and 5G-wireless access networks * Inter- and intra-data center communications * Free-space and quantum communication links Another key issue is the use of advanced photonics manufacturing and electronic signal processing to lower the cost of services and increase the system performance. To address this, the book covers: * Foundry and software capabilities for widespread user access to photonic integrated circuits * Nano- and microphotonic components * Advanced and nonconventional data modulation formats The traditional emphasis of achieving higher data rates and longer transmission distances are also addressed through chapters on space-division-multiplexing, undersea cable systems, and efficient reconfigurable networking. This book is intended as an ideal reference suitable for university and industry researchers, graduate students, optical systems implementers, network operators, managers, and investors. Quotes: "This book series, which owes much of its distinguished history to the late Drs. Kaminow and Li, describes hot and growing applied　topics, which include long-distance　and wideband systems,　data centers, 5G, wireless networks, foundry production of photonic integrated circuits, quantum communications, and　AI/deep-learning. These subjects will be highly beneficial for industrial R&D　engineers, university teachers and　students, and funding　agents in the business sector." Prof. Kenichi IgaPresident (Retired), Tokyo Institute of Technology "With the passing of two luminaries, Ivan　Kaminow and Tingye Li, I feared the　loss of one of the premier reference books in the field. Happily, this new version comes to chronicle the current　state-of-the-art and is　written by the next　generation of leaders. This is a must-have reference book for anyone　working in or trying to understand　the field of optical fiber communications　technology."Dr. Donald B. Keck Vice President, Corning, Inc. (Retired) "This book is the seventh edition in the definitive series that was previously marshaled by the extraordinary Ivan Kaminow and Tingye Li, both sadly no longer with us.　　The series has charted the　remarkable progress made in the field, and over a billion kilometers of optical fiber currently snake across the globe carrying ever-increasing Internet traffic.　Anyone wondering　about how we will cope with this incredible growth must read this book." Prof. Sir David Payne Director, Optoelectronics Research Centre, University of Southampton * Updated edition presents the latest advances in optical fiber components, systems, subsystems and networks * Written by leading authorities from academia and industry * Gives a self-contained overview of specific technologies, covering both the state-of-the-art and future research challenges
