"Optical fiber communication technology enables ultrahigh-speed, high-capacity, long-distance transmission. Recent Developments in optical communication such as dynamic-single-mode lasers, low-loss single-mode fibers of low dispersion and sensitive InGaAsP-avalanche photodiodes with fast response lead to fiber systems with pulse rate regenerator distance products of 25 Gbit km/s per fiber. Because there is no unconventional technology, it is vital basic infrastructure underneath society’s information and communication functions. The spread and improved performance of photonic infrastructure thus has a major influence on a country’s overall social life. For instance, mobile telephones using wireless to reach nearby antenna stations, but the stations utilize photonic networks among themselves, and optical-fiber cables on the ocean floor facilitate real-time communication with people all over the world. Optical Fiber Communication covers recent advances and development in optical fiber technology associated to the next generation optical communication, system and network, sensor, laser, measurement, characterization and devices. The contributed chapters are from eminent scientists and researchers involved in cutting edge research in this field. Portraying an overall view of current research trends and technology on these topics, this book will be of interest for practicing researchers, academics, practicing students, and other scientists to review, plan, design, analyze, evaluate, intend, process, and implement diversiform issues of optical fiber and wireless systems and networks, optical technology components, optical signal processing, and security."
