Abstract: This paper studies and discusses the current status of services and equipment such as power supply system, data network, transmission network, and access network of Beijing-Guangzhou line, and proposes different optimization schemes for different types of services. Overdue service equipment is disabled, key service channels involving optical cables, power supply, transmission, data and other networks are rationally optimized and shared  on two sets of equipment, so as to achieve the four dual goals of dual power supplies, dual devices, dual paths and dual systems and ensure the maximum reliability of service carrying.

Key words: power supply system, data network, transmission network, access network, optimization
