The Research Of Ftth Planing And Design

With the continuous promotion of the rapid increase in demand for high bandwidth and network multimedia applications, the Beijing Government20M FTTH broadband development strategy. Large-scale FTTH construction is to meet the tri-networks integration,20M high-bandwidth business needs, the only way to provide guaranteed video services. With the conduct of business of the family of broadband multimedia platform, only to realize optical access for users to carry out high-bandwidth services. Therefore, the transformation of traditional DSL access way is imperative, fiber to the home will become necessary to meet20M bandwidth. EPON technology is more mature industrial chain from chip to the device is more robust, more manufacturers at home and abroad to provide EPON equipment costs are also declining, the EPON broadband optical access and FTTH is currently one of the ways. Type of technology used, the access method and how to implement the focus from the old residential copper access to fiber access is also this study and exploration.The goal of this study is the design of Beijing Unicom FTTH master plan. Research ideas to the key technologies of EPON and GPON, the combination of FTTH in the status of domestic and foreign design. The final research results through practical projects to verify that the design is feasible and, ultimately, the transformation of fiber to the home.The first chapter describes the background and positive significance in the Music City FTTH project modification. The second chapter analyzes the current PON technology of the mainstream, and a detailed study of the mode of operation and technical characteristics of the EPON EPON and GPON two techniques were compared and analysis. The third chapter describes the development trends and current situation of the domestic and international fiber to the home of EPON-based fiber to the home network model has been studied. Chapter IV of the Beijing Unicom FTTH overall design programs and standards, In the fifth chapter a detailed description of an instance of the music into the international district FTTH transformation of the construction program, Including the construction of the infrastructure of PON equipment, fiber optic cable laying, data planning, and cutover of the process of transformation and post-maintenance of our experience.The paper concludes with a future development strategy of the fiber to the home, provides a reference for telecom operators. The author proposed by comparison of two PON technology analysis based on EPON FTTH design, Fiber transformation of the construction of Beijing Unicom to provide the direction of development, and design was verified by the actual project has achieved good results.
