基于EPON系统的ONU LSW数据接收控制器设计

Design of Transmitting Controller in EPON System

随着三网融合技术的发展,EPON系统正以其低成本、高带宽等优点成为接入网的主流技术之一.提出了一种EPON系统ONU LSW数据接收控制器的设计方案,在简要介绍数据接收处理逻辑总体结构的基础上,详细分析了各个子模块的设计思路,重点阐述了数据接收处理逻辑的状态机控制过程及数据传输的格式,最后编写验证平台对设计进行了功能仿真,并对仿真波形进行了分析.

With the development of integration of three networks, EPON system advantages into one of the mainstream technolo- gy of access network. Article presents a design of EPON ONU LSW data reception controller. On the basis of introducing the o- verall structure of data receiving and processing logic, analyzes the details of all the child module designs, mainly interprets the state machine of data receiving and processing logic and data transmission format, simulates the function of the design with Test- bench and analyses the simulation waveform.
