Features: This book comprehensively introduces the fundamental knowledge and testing methods of the Synchronous Digital Hierarchy (SDH). The book is divided into three parts. Part 1 covers the basics, introducing the concept of SDH, basic signal structures, multiplexing and mapping structures, technical specifications of system optical interfaces, system bit error rate (BER), jitter, and drift performance requirements, as well as SDH equipment types and synchronization and quantization methods. The second part provides detailed explanations of the corresponding testing methods for various indicators and functions of SDH optical cable line systems (some chapters include testing methods for equipment and networks). The content includes optical interface testing, electrical interface testing, jitter and drift testing, bit error testing, timing synchronization and clock testing, protection switching testing, loopback function testing, overhead and maintenance signal testing, etc. This book is suitable for engineering technicians and management personnel engaged in the research and development, planning and design, construction, and maintenance management of SDH systems and equipment. It can also serve as a reference for faculty and students of relevant disciplines in communication schools.
