Practical Research For Optical Network Using In Railway Marshalling Station

Using Optical Network integrated platfrom transmission,access and voice ,data,image exchange is a trend of the communication networks and achieved shared system resources. Moreover, with the development of the technology improved performance and cost decreases,Optical Network will be more and more useful in many field . Optical Network not only apply to long-distance, large-capacity transmission, but also apply to information transmission within MAN(Metropolitan Area Networks). Every railway marshalling station need more widely bandwidth with the increasing workload Using Optical Network for access and transmission is a trend for future ,becasue optical fiber provide widely bandwidth and declining cost .The flexibility of optical network can satisfy the demand of railway marshalling station. It has bright future, and make a new model of the marshalling station modernization.The country's marshalling station communication technology has reached top level.This paper intended to the study of three aspects.Start with researched network patterns .Study of the marshalling station network, related to demand and work experience,designed and improved a network patterns. Secondly, gained knowledge about Optical Network through detailde research. Finally, combination of two aspects of research above, designed a optical transmission network adapt for marshalling station network. Put forward a method which build a marshalling station network without optical amplifier, it can greatly reduce the costs of building a marshalling station All Optical Network.
