Research on Networking of the Large Capacity Power Backbone Transmission Network Based on Cross Technology

The 12th Five-Year Plan requires the power backbone transmission network to be with large particles and high bandwidth. The new technology-OTN can meet the requests. In addition, OTN makes up for the limitation of small particles transmission of SDH and the defects of WDM networking. Cross is the key technology of OTN. OTN electrical, optical and photoelectrical hybrid cross techniques and their advantages and disadvantages are introduced in this paper. At last, three kinds of cross network strategies are put forward to meet the needs of the future development of Power backbone transmission network, which make the theoretical foundation for the construction of the net.
