【摘要】：无源光网络(PON)是在当前形势下,应对日益增长的高带宽远距离数据通信需求的有效解决方案。以太网无源光网络(EPON)因其与现有以太网络设备兼容性好,技术实现容易,总体成本较低等优势,运营商推动着EPON在电信接入网络的大规模商用化。随着无源光网络标准的发展和技术的成熟,以EPON标准为代表的无源光网络向工业领域专用网络渗透,如电力PON,铁路PON等。 工业领域专用网络,不仅对光网络的可靠性提出更高的要求,而且其业务接口相较于家庭宽带接入更加多样化和差异化,如铁路区间光通信系统,要求具有2路数据口和4路电话口,支持双PON口保护功能。而市场上现有的EPON ONU SOC方案基本都是针对家庭宽带接入设计的,并不能很好的匹配工业领域专用网络的业务需求特点,扩展也不够灵活。 本课题面向工业领域专用网络,提出EPON ONU SOPC设计方案。采用了Xilinx公司Zynq处理器平台,ARM+FPGA体系架构,All Programmable SoC解决方案,通过可编程逻辑实现,IP核复用技术以及上层软件库实现等,构建EPON ONU SOPC系统,以此满足工业领域专用网络对业务种类和接口数量等的差异化需求。 本文首先在对EPON相关国内外标准的研读基础上,详细介绍了EPON ONUMAC的逻辑设计实现,然后基于Zynq平台和Digilent公司ZedBoard板卡进行SOPC系统硬件平台的构建。由于ZedBoard未包含光接口,本文还介绍了双PON口FMC扩展板卡的相关设计实现。 最后,使用瑞斯康达公司的OLT设备(ISOCM5508)搭建了简易的EPON网络测试环境,对Zynq SOPC硬件平台构建以及EPON ONU MAC IP核的操作进行验证和测试,测试结果显示,ONU正确注册并运行,达到了EPON ONU SOPC硬件设计目标。
[Abstract]:Passive optical network (PON) is an effective solution to meet the increasing demand for high bandwidth and long-distance data communication under the current situation. Ethernet passive optical network (EPON) has many advantages, such as good compatibility with existing Ethernet equipment, easy technology implementation, low overall cost, and so on. Operators promote large-scale EPON in telecommunications access network. With the development of passive optical network standard and the maturity of technology, the passive optical network represented by EPON standard has penetrated into the industrial private network, such as power PON and railway PON.
Private networks in the industrial field not only require higher reliability of optical networks, but also have more diversified and differentiated service interfaces than home broadband access. For example, railway optical communication systems require two-way data ports and four-way telephone ports to support dual-PON port protection. They are designed for home broadband access, and can not well match the characteristics of the business needs of the industrial domain private network, and the expansion is not flexible enough.
This paper presents the design scheme of EPON ONU SOPC for industrial domain dedicated network. It adopts Xilinx Zynq processor platform, ARM+FPGA architecture, All Programmable SoC solution, and constructs EPON ONU SOPC system through programmable logic implementation, IP core reuse technology and upper software library implementation to meet the industrial domain dedicated. The differentiated demand of network for business type and number of interfaces.
This paper first introduces the logic design and implementation of EPON ONUMAC on the basis of studying the relevant domestic and foreign standards of EPON, and then builds the hardware platform of SOPC system based on Zynq platform and ZedBoard card of Digilent Company.
Finally, a simple EPON network test environment is built using Resconda's OLT equipment (ISOCM5508). The hardware platform of Zynq SOPC and the operation of EPON ONU MAC IP core are verified and tested. The test results show that ONU is registered and operated correctly, and the hardware design goal of EPON ONU SOPC is achieved.
