摘要
的普及,宽带接入已逐渐成为电信业新的业务增长点。IPTV、视频会议、视频聊天、网络游戏、VoIP等新业务和应用的出现对目前接入网和带宽提出了更高的要求,现有的xDSL或LAN等接入方式很难满足未来的需求。由于EPON与以太网有很好的兼容性,并具有高带宽、传输距离远、网络中没有有源器件、低成本等优点,随着技术的成熟和市场需求增长,EPON已是下一代宽带综合接入的最佳技术。但在实际应用中,不同用户的QoS要求、带宽需求、地理分布疏密及距离电信端局远近都不尽相同,因而,EPON的实际应用情况也各不相同,需要根据不同的情况灵活组网。下面我们针对常见用户的接入方案进行了设计。区域发展不平衡,对业务需求不一,并且用户地理分布疏密不均,不同用户带宽和QoS需求不一,呈现不确定性。考虑到占领市场和投资的经济,针对用户类型和地理分布等特点,采用基于EPON多种接入技术混合的接入方式,实现最优化接入。

Abstract
With the popularization puter users and the rapid growth of , broadband access has gradually e a new growth point of industry. IPTV, video conferencing, video chat, online games, VoIP and other new services and applications for higher current work and bandwidth requests, the existing xDSL or LAN access method is difficult to meet the needs of the future. Because EPON and has patibility, and has high bandwidth, transmission distance, work does not have active devices, low cost, with the mature technology and market demand growth, EPON is the best technology for next generation broadband integrated access. But in practical application, the different QoS requirements of users, the bandwidth requirement, the geographical distribution of density and distance munication terminal distance are not the same, therefore, the actual application of EPON also each are not identical, according to the different needs of the working. Below we mon users access scheme is designed. The imbalance of regional development, the needs of the business is not a user, and geographical distribution of uneven density, different user bandwidth and QoS requirements are different, presenting uncertainty. Taking into account the occupation of the market and investment in the economy, according to the characteristics of user types and geographical distribution, the access mode of EPON multiple access technology to realize the opt
