Epon Network System OLT Lord Card System Design

In the information society, the spread of all kinds of information and communication becomes more and more frequent. Thus, social to communication network service demand is constantly increasing. Thus access network became restricted the whole network development of a bottleneck. Based on Ethernet passive optical network technology development becomes the international development trend of the latest access network, also become the research focus of the broadband access.EPON international standard IEEE802.3ah since2004after issued. As broadband access the development of the market got large-scale business. According to the statistical data RHK. From the first quarter of20071began. EPON in all sorts of piping pick up person accounts for the technology market share. Rapid growth and has been in absolute leading status. Especially in2008, domestic operators EPON choice as light into copper back solution. Further established EPON in fiber access market dominance. Along with the video and the development of new business. The user the demand for bandwidth is also growing. EPON technology will continue to meet the needs of the users are constantly development. This paper EPON the latest development of the technology is introduced and analyzed. That in the next FTYX EPON technology development trend and the leading position.This paper is based on a EPON equipment product development, main is a deep research network system of EPON OLT equipment parts of the hardware system design and relevant driver development. And, on the related researches on some of the network technology and embedded developing technology application. Related design to Vxworks real-time operating system, relevant equipment driver and BSP development, and some of the basic network exchange agreement part of the research.This paper mainly through a central part of the development process of the system through show and explain the development environment is introduced and its related part of research to clarify the driver of the whole system development process and its related results show. The paper also through the relevant theoretical knowledge introduction and to the technical characteristics of this EPON and related development tendency and the background knowledge.
