The technologies of fixed and mobile broadband access provide users with a better quality of network services.While it puts forward higher requirements on the capacity of transmission network

also the complexity and risk for the fiber trunk cable group cutover have been increased.Based on the research and practice experience for cable cutover

this paper proposed the specification process of fiber trunk cable group cutover in transmission network

which could reduce the complexity and ensure error-free in the daily work.It shows an important guiding significance for practical work
