Use of multiple sensors in a network (multiplexing) is cheaper while retaining the benefits of fiber optic networks. This book shows readers how to take into account various modulation techniques, network topologies, and decoding methods when designing a network. It deals with multiplexing networks for point and quasi- distributed optical fiber sensors and explains the principles of these systems, their components, and categorization. The author compare and contrast various multiplexing networks for optical fiber sensors, including those based on optical amplification and lasing multiplexing systems, and presents several illustrative examples.
