Features: The book is divided into 8 chapters. It primarily introduces the basic structures of communication networks, the development process of communication lines, and the transmission standards of wired telecommunication networks. It covers the structure, types, model representation, terminal identification, and electrical performance parameters of communication all-plastic cables, coaxial cables, and twisted pair cables used in data communication. The book also explains the procedures, methods, and steps of various construction forms in cable lines, focusing on user cable line wiring methods, including cross-connect wiring, direct wiring, and common distribution equipment. Additionally, it discusses electrical testing methods for cable lines, including testing for loop resistance and shield resistance of user lines, insulation resistance, grounding resistance, as well as intelligent testing and pinpointing of cable line faults. The book covers the maintenance of communication cable lines—user cutover and gas-injection maintenance—as well as the protection of cable lines, primarily focusing on preventing strong electric interference, lightning strikes, and pest infestations. It also includes cable line survey and design. The book follows the principles of practicality and systematic organization, emphasizing published industry standards and regulations to achieve the goal of "learning and applying immediately." The content is easy to understand and closely tied to real-world applications. The book is richly illustrated with completed project drawings from actual engineering projects, making it highly practical. It can serve as a textbook for higher vocational and technical college communication majors, a training manual for various communication line engineering courses, and a reference for engineering technicians.
