This Introduction to DWDM Technology is intended for readers who want to gain a basic understanding of dense wavelength division multiplexing (DWDM) technology and its role in metropolitan area networks (MANs). The contents are organized as follows:

Chapter	Title	Description
Chapter 1	Introducing DWDM	Differentiates the MAN from other segments of the global network; describes the driving forces behind DWDM; contrasts time division multiplexing (TDM) with wavelength division multiplexing (WDM); presents the advantages of DWDM in the MAN
Chapter 2	Fundamentals of DWDM Technology	Summarizes the evolution of fiber optic transmission and DWDM technology; briefly describes the main components; explains the operation of a DWDM system
Chapter 3	DWDM in Metropolitan Area Networks	Surveys the data link and network technologies used in the MAN; describes sample applications for DWDM; presents sample topologies and protection schemes; offers practical considerations for deploying DWDM

Readers who are interested in more detailed information about optical networking will find that there is a wide selection of resources available, especially on SONET. The following publications are good, basic texts:

•Dutton, Harry J. R. Understanding Optical Communications. Research Triangle Park: IBM Corporation; 1998.

•Goff, David R. Fiber Optic Reference Guide, 2nd edition. Boston: Focal Press; 1999.

•Goralski, Walter J. SONET, 2nd edition. New York: McGraw-Hill; 2000.

•Kaminow, Ivan P., and Koch, Thomas L., eds. Optical Fiber Telecommunications. San Diego: Academic Press; 1997.

The following publication is a detailed text on DWDM, particularly from the standpoint of theory and optical components:

Kartalopoulos, Stamatios V. Introduction to DWDM Technology: Data in a Rainbow. New York: IEEE Press; 1999.

Although comprehensive texts specifically about DWDM are not yet plentiful, there is a variety of information in the form of tutorials, white papers, and so on, to be found on the World Wide Web.
