| Abstract: | With the ever change of business needs, the traditional transmission network has been unable to efficiently carry the IP business, and no longer suitable to the trend of A11-IP development, thus it is necessary to adopt new transmission network technology. The paper, by analyzing the flaws of traditional WDM technology tells of a new generation of network transmission technology OTN and its standards, system architecture, frame structure, signal mapping and multiplexing, equipment classification, and other technical features, and analyzes the strengths and weaknesses of the OTN technology. It is believed that OTN, one of the best transfer technologies for broadband data service, would be widely used in the near future. |
