Research on the Application of OTN Technology in Fiber Optic Transmission Access Networks
In order to optimize the quality of optical fiber transmission and meet the requirements of controllable management of broadband access,the technical specifications of application control of optical fiber transmission should be strictly followed,an Optical access Network based on Optical Transport Network(OTN)technology is established to maintain the timeliness of information transmission and build a complete technical operation framework.The application content of OTN technology should be systematically analyzed from the aspects of large particle information transmission and processing,metro core network and trunk network,broadband user access,long-distance network application cross-equipment,etc.,therefore,the smooth upgrading of network performance can be better realized,and the specific requirements of man construction can be satisfied.Therefore,it is of practical significance to systematically study the application of OTN technology in optical fiber transmission access network.
