Taking Zibo Yuezhuang 220kV supporting communication project as an example
this paper introduces the development of electric power optical communication networks in Shandong and presents a communication application program by the aid of the combination of the provincial Optical Transport Network(OTN)circuit with the regional SDH and Packet Transport Network(PTN)circuits
enhancing the substation information transmission channels.
