In the context of the construction of a new power system,"accelerating the transformation and upgrading of the distribution network,promoting the construction of intelligent and active distribution networks,improving the carrying capacity and flexibility of the distribution network to accept new energy and diversified loads,and promoting the priority of local development and utilization of new energy"has become an important task.With the accelerated construction of intelligent distribution networks,in order to better support the four remote applications of"remote sig-naling,telemetry,remote control,and remote adjustment",the coverage range and scale of the terminal communica-tion access network fiber optic private network will be rapidly improved.There are more and more access network constructions based on Passive Optical Network(PON)technology.The current construction mode of PON net-works in the power grid is mostly a tree structure networking mode,and the placement of splitters is extremely par-ticular.It is necessary to comprehensively consider not only the access of current terminal Optical Network Unit(ONU)equipment,but also the access and estimated number of ONU equipment for future construction of terminal sites.Therefore,the placement of the spectral splitter and the type of spectral ratio selected are extremely important.
