This book provides the first industry-oriented, comprehensive coverage on DWDM network designs and engineering solutions. Dense wavelength division multiplexing (DWDM) is the optical transmission of multiple signals. There is no one source that explains the details of designing/building a DWDM network from the ground up. DWDM Network Designs and Engineering Solutions is an all-out practical approach that teaches the reader new technologies and ways to plan, design, and build their networks in a real-time environment. Each chapter begins familiarizing the reader with new technologies and then helps implement the same in practical, real-world case studies. This book enables network designers to tap the huge bandwidth offered by fiber to the fullest and makes the vision of an Optical Internet come true.
