In recent years

with the proposal of the construction idea of "expanding the deployment scope of gigabit optical network and supporting Gigabit service development"

higher requirements are put forward for network bandwidth. Based on the construction idea of "one optical cable network"

aiming at the problems of shortage of basic network resources and chaotic management in the integrated service access area

this paper puts forward an optimization scheme and rational allocation of optical network resources

so as to lay a good foundation for network construction in the future.
