Troubleshooting and Maintenance of SDH Optical Transmission System

This paper introduces the fault classification of SDH optical transmission system, describes the location of the fault and the processing method of the fault. Finally summarized the content and specific requirements of the maintenance of SDH optical transmission system. Combined with the actual operation and maintenance work, the basic configuration and function of SDH equipment are described, and the specific application of SDH equipment in Xianning power communication is analyzed Using the basic principle of SDH and the theoretical basis of mapping process, this paper discusses the methods to solve the major and difficult faults in actual maintenance work The treatment and analysis process of common faults in daily operation and maintenance of SDH optical terminal equipment and some problems in daily maintenance are summarized and summarized
