Understanding Fiber OpticsIdeal for technicians, entry-level engineers, and other non specialists, this practical, thorough, and accessible introduction to fiber optics reflects the expertise of an author who has followed the field for over 20 years. Using a non-theoretical/mathematical approach, it begins with the technical details of optical fibers, moves through the tools and techniques used to work with them, the devices used to connect fiber network, and concludes with applications showing how fibers are used. *NEW-Provides full explanations of fiber types, characteristics, and materials. *NEW-Offers up-to-date explanations of fiber amplifiers and fiber gratings. *NEW-Explains wavelength-division multiplexing and dense WDM (DWDM) systems. *NEW-Discusses optical switching and networks. *NEW-Explores fiber-optic systems for distribution to subscribers - including fiber to the curb and hybrid fiber-coax. *Describes the evolution of fiber-optic technology and its applications to communications. *Considers the characteristics, manufacture, operation, and function of major types of fibers. *Demonstrates basic splicing concepts, loss mechanisms, fusion splicing, and mechanical splicing. *Reviews long-distance |
