Features: All-optical communication networks can eliminate the bottleneck of electronic switching, enabling high-capacity signal transmission and switching, which is the ideal goal pursued in optical communication. Building upon the existing multi-wavelength DWDM transmission, developing optical transport network (OTN) technology based on wavelength switching and routing is the necessary path to achieving all-optical communication networks and the preferred solution for current communication network upgrades. Thus, it has become one of the most closely watched hotspots in the field of optical communication. This book begins by introducing the characteristics and development trends of optical transport networks, comprehensively covering the relevant technologies of OTN equipment. The content includes the functions of OADM and OXC nodes in the network; descriptions of the functional roles of OTN equipment at each layer (OCh, OMS, OTS); the latest advancements in key OTN node technologies (tunable devices, wavelength conversion, all-optical regeneration, channel crosstalk, power equalization, etc.); OTN equipment management; and OTN equipment monitoring. This book references the latest ITU-T recommendations and systematically collects current research materials on OTNs from both domestic and international sources. The book is well-organized, with up-to-date content, strong systematicity, and practicality. It is suitable for professional technicians and engineers with some communication knowledge, as well as for college and university students who wish to systematically study cutting-edge technologies in modern optical networks.
