Features: Chapters 1-10 of this book introduce Synchronous Digital Hierarchy (SDH), covering the following content: the concept of SDH, signal structure, multiplexing and mapping, optical and electrical interfaces, transmission impairments (bit error, jitter, and drift), equipment and network applications, SDH network management systems, and an introduction to next-generation SDH products. Chapters 11-16 introduce Wavelength Division Multiplexing (WDM) systems, covering the following content: the concept of WDM, optical fibers and cables, key components and technologies, WDM system technical requirements, WDM network management systems, and an overview of future optical networks. The book takes technical standards as the main thread, combining fundamental theories with practical engineering applications. It is clear in concepts, strong in logic, and maintains the "authenticity" of technical standards while remaining easy to understand. Each chapter also includes review questions for reference. The SDH and WDM technical specifications in the book adopt the latest version of recommendations from the International Telecommunication Union Telecommunication Standardization Sector (ITU-T). It explains the differences between the latest version and previous versions of several important recommendations. Since many domestic standards still adopt equivalent versions of the original recommendations and are yet to be revised, this part of the content is highly practical. The book is suitable for undergraduate students of communication engineering in universities, as well as working professionals and maintenance personnel in the field of optical communications.
