一种机动无源光接入系统的应用研究

Applied research on an mobile passive optical access system

针对各种重大突发事件发生所导致信息实时传送阻断问题,研发了一种灵活应用的机动应急光接入系统,在硬件、软件及接口等技术基础上,进行了系统管理软件关键技术的设计,阐述了链路测试过程并进行了组网应用。测试结果表明:从源端到目的端的吞吐量为75.47Mb/s(TCP)和20.56Mb/s(UDP)。通过在不同地理位置,分别选择8km、13km和18km的传送距离进行语音、数据、图像及视频等多业务试用,信号传输正常、网络运行稳定。

In view of the problem of the real-time transmission interruption of information caused by all kinds of serious emergencies, a mobile emergency optical access system which can be applied flexibly is developed. On the basis of hardware, software and interface technologies, the key technology of system management software is designed, the link test processing is expounded and the networking is applied. Link test results： The throughput from the initiator to the destination is 75.47 Mb/s（（TCP） transmission control protocol） and 20.56 Mb/s（（UDP） user datagram protocol）. In different geographic locations, the transmission distance of 8 km, 13 km and 18 km is respectively selected for multi-service trials, such as voice, data, image and video. The results show that the signal transmission is normal and the network runs steadily.
