摘　　要：文章给出3种基于EPON技术的电视信号接入技术方案,目的是解决宽带电视信号在智能小区内可靠传输的问题。文章分析了各种用户应用对通信带宽的需求,结合现场工程实施情况,选择不同的电视信号接入方式。每种方式均能较好地满足用户应用需求,并将设备和施工的综合成本降到最低。实践证明,文章提出的3种基于EPON技术的接入方案可有效指导大部分智能小区电视信号接入的工程实施。This paper introduces three schemes based on EPON for TV signal accessing, in order to achieve the reliable transmission of TV signal in the smart district. This paper also analyzes the bandwidth demand from different applications. It then proposes three schemes for TV signal accessing, considering the field project situation. Each scheme can satisfy the demand from various kinds of applications, and reduce the whole cost of the equipment and the construction. It is proved by practice that the three schemes mentioned in this paper can effectually guide the construction of TV signal accessing in the intelligent community.
