Interoperability Research And Implementation For EPON Systems

In recent years, along with the development of communication technique, network transmission ability has been improved a lot. However, the main mode of copper cable's communication can not adapt to the current communication development. At the same time, with the development of connect technology and the cheaper fiber, the fiber access network appears. It combines the advantages of PON and Ethernet.With its feature of high bandwidth,low cost,and being used and updated easily, EPON is one of the best solutions to broadband access Network.In this thesis,the most important part is the interoperability analysis and research for EPON system,which is divided into three layers: the interoperability of EPON basic function, the interoperability of service carrier function,and the interoperability of operation,administer, maintenance function. The thesis makes a further research based on the test of the interoperability for EPON system,and summarizes the questions in the test.It is vital for the widely used of EPON system.This thesis is divided into six chapters:Chapter one gives the background of researches and meanings of the thesis.Chapter two provides the simple introduction of AN and the bandwidth access techniques. Chapter three analyses the layers of EPON system, Multi-Point MAC Control Protocol and Multi-Point MAC Control system. Chapter four researches the key tecniques of EPON system,such as the process of distance measuring and Dynamic Bandwidth Allocation.Chapter five is the most significant part of the whole thesis. It gives a deep investigate in the interoperability for EPON system,besides it discusses the problems in the interoperability for EPON system. Chapter six summarizes the whole thesis,and offers the advices for the further work.
