EPON系统中ONU告警仿真的设计与实现

摘要

In EPON system engineering applications, it is difficult to test ONU alarm processing capability under large-scale engineering applications in the laboratory environment using limited ONUs. In this paper, an idea is proposed to use the simulated ONUs to emulate alarm. Experimental results show that this design could completely meet the demand, reduce the test complexity of EPON systems, shorten the test time of EMS and save test cost. 'Ihis method has important reference value for promoting the industry development.%在EPON系统工程应用中,如何在实验室环境下,用有限的ONU设备,测试大规模工程应用条件下EMS对于ONU告警的处理能力,一直是困扰业界的难题.创新地提出了采用模拟ONU进行告警仿真的思想.经实验验证,该设计完全可以满足需求,降低了EPON系统测试的复杂度,缩短了EMS测试周期,节省了测试成本,对于促进行业的发展有着重要的参考价值.
