Beijing Unicom Gpon Broadband Access Network Reserch And Design

Technology and application of GPON is developing rapidly. It has become one of the hot technology in the world. Beijing Unicom GPON is also actively involved in the testing and building, I had the privilege to participate in the Beijing Unicom GPON project design, construction and implementation. The work of the papers from the Beijing Unicom actual projects.The paper study this branch based on the existing broadband network of Fangshan, Beijing Unicom, combined with the current development of PON access technology research at home and abroad made the GPON broadband network transformation program, the program implements the data, voice and video integrated service access, is to achieve "triple play" and solve the information superhighway "last mile" of the best transmission medium.This paper describes the application of broadband network status at home and abroad, By analyzing the various types of broadband access technology defined GPON technology in broadband network development advantages. Then introduces Ethernet-based PON network, summarizes the current mainstream technology FTTx, PON standard status, and briefly describes the implementation of GPON principles, key technologies and technological advantages.The paper focuses on analyzing the application of GPON in the subscriber access network. First, the status of the access network is analyzed, due to proximity to existing ADSL network transmission, bandwidth is limited, you need a fixed room, the problem of higher construction costs, special district is proposed buildings will be used in GPON solution, the next paper summarizes in GPON deepen the implementation of the design elements of the process, a brief description of OLT, ODN and ONU building address, the process of project implementation from the other elements. GPON access network used to verify the feasibility, we GPON technology in voice, data and Internet services and other aspects of test papers and results of the test program is described in detail, the test for the article analyzes the business buildings in the district of GPON provide a reference and foundation.Fiber access network access is the development trend of access network. At present,GPON technology has gradually matured, the costs have been declining and its functions have been ameliorated. GPON have been widely used in domestic and abroad. GPON technology will be more and more usable.
