【摘要】 针对光通信网络实践教学资源不足的问题，设计了一套虚实结合的全光接入网实践教学系统。以通信业务开通任务为主线，在全光接入网现网设备基础上构建全真式实践教学系统，采用软硬结合方式模拟应用层服务器及通信用户终端，规划从应用层服务器经全光接入网到通信用户终端的配置信息，测试验证各类通信业务开通成功与否。以网络故障排除任务为主线，利用虚拟现实技术开发全光接入网虚拟仿真实验教学系统，构建涵盖中心机房、光缆交接箱、校企联合实验室的虚拟校园应用场景，集中展现光分配网络、多业务网关、光线路终端和应用层服务器相关的故障问题。实践表明，该实践教学系统的设计与应用既提升了教师的光网络实践教学资源建设能力，又培养了学生解决复杂光网络应用问题的实践创新能力。更多还原

【Abstract】 Due to the lack of practical teaching resource of optical communication network, an all-optical access network practical teaching system based on virtual-real combination is designed. The communication service opening is regarded as main task, a real practical teaching system is built based on all-optical access network commercial equipment. The application layer server and communication user terminal are simulated by software and hardware combination. Configuration information from application layer server to communication user terminal through all-optical access network is planned and the success of various communication services opening is verified. The network troubleshooting is regarded as main task, a virtual simulation experiment teaching system of all-optical access network is developed by utilizing virtual reality technology. The virtual campus application scenarios including central office, fiber distribution terminal and university-enterprise joint laboratory are constructed. Concentrated presentation of optical distribution network, multi-service gateway, optical line terminal and application layer server related network troubles is realized. With the design and application of this practical teaching system, the teachers’ construction ability of optical network practical teaching resources is improved, and the students’ practice and innovation ability to solve complex problems in the application of optical network is cultivated.更多还原
