摘　　要：在贵州地区电力通信网络的建设中,长站距传输是一个必须考虑的问题。文章介绍了为在贵州电网综合数据网新平面工程中,采用超长距无中继传输技术,实现省干综合数据网至省内地、市供电局超300公里范围内的无任何中继、中途放大器等设备的直连通信的目的,利用SBS抑制技术、超强前向误码纠错技术、分布式拉曼放大技术,波长转换技术等技术手段,实现了电力超300km光通信工程中超长站距无任何中继、中途放大器等设备的直连方法,并成功开通单跨72dB 10G超长距大容量通讯系统。通过超长距离传输技术的应用,可节省光纤路由通道、OTN传输设备等资源,同时能够达到长距离传输的大带宽稳定通道可保障多种路由组织方式,进一步增强电力通信系统的安全可靠性,为超长距大容量传输系统在贵州省复杂应用环境中的部署提供理论及实践指导。In the construction of power communication networks in Guizhou, long-distance transmission is a problem that must be considered. In order to adopt ultra-long distance non-relay transmission technology in the new plane project of Integrated Data Network of Guizhou Power Grid, to achieve the goal of direct communication between the provincial trunk integrated data network and equipment such as repeaters and intermediate amplifiers within 300 kilometers of the provincial inland and Municipal Power Supply Bureau, using SBS suppression technology, super forward error correction technology, distributed Tunku Abdul Rahman amplification technology, wavelength conversion technology and other technical means to realize the ultra-long station distance without any relay in the ultra-300 km optical communication project. The direct connection method of equipment such as the mid-way amplifier and successfully opened a single-span 72 dB, 10 G, ultra-long-distance and large-capacity communication system is successfully opened. Through the application of ultra-long-distance transmission technology, resources such as optical fiber routing channel and OTN transmission equipment can be saved, while the large-bandwidth stable channel for long-distance transmission can be achieved, which can guarantee various ways of routing organization, to further enhance the security and reliability of power communication system, to provide theoretical and practical guidance for the deployment of ultra-long distance and large capacity transmission system in Guizhou province.
