Abstract: With the increase of urban rail transit operating lines, it is necessary for the transmission network to provide sufficient bandwidth capacity and reserve enough expandable space for future new business and line growth. This article takes the construction of the A city rail transit network transmission system as an example, analyzes and studies the network transmission system, compares three transmission technology standards, proposes a construction plan for the network transmission system, and discusses the construction of the rail transit transmission system.
