| Abstract: | The fast growth of electric power network services brings a higher requirement to the telecommunication bandwidth. Under the new circumstance, electric power telecommunication transport network must have the properties of high capacity, long distance and high stability. This paper introduces the OTN technique satisfying all the above requirements, including its electric layer payoff structure and system state properties. Further, the ASON protection scheme supported by the OTN is tested in a real network. The testing results show that choosing the protection schemes reasonably can greatly reduce the protection shift time, which has a guiding significance for applications of the OTN technology in Jilin electric power telecommunication backbone network. |
