Internet information (which is doubling every six months) travelsthrough optical fibers. Today, optical fibers are being installedwhere a single fiber has the ability to carry information as much as200 times faster than was possible just five years ago. Thisrevolutionary capability is being achieved with technology known aswavelength division multiplexing WDM). WDM technology relies on thefact that optical fibers can carry many wavelengths of lightsimultaneously without interaction between each wavelength. Thus, asingle fiber can carry many separate wavelength signals or channelssimultaneously.The communications industry is at the onset of newexpansion of WDM technology necessary to meet the new demand forbandwidth. This book deals with the Networks facet of this field(present and future).* Allows engineers working in opticalcommunications(from systems to components) to understand theprinciples and mechanics of each key component they deal with foroptical system design.* Provides an excellent resource for engineersand researchers engaged in all aspects of fiber optic communications,such as optoelectronics, equipment/system design, and manufacturing.*Provides comprehensive coverage of key concepts in optical networksand their application in commercial systems.
