2.5G 726 km与10G 681 km超长单跨距传输系统的设计与研究
|
摘要
随着泛在物联网概念的提出,电力通信系统对大容量、无中继、超长距离传输的需求将大幅提升。实验通过使用高阶拉曼放大技术、增强型高浓度遥泵放大技术、多旁路远程泵浦技术和相干光传输技术,以大有效面积G.654.E光纤为传输介质搭建了一套超长距无中继光传输系统。实现了2.5G系统726 km、10G系统681 km无中继传输,这是目前可查文献中2.5G与10G系统所达到的最长传输距离。实验成果为衡量大容量超长距无中继传输系统性能、指标提供了实验依据和参考。
With the ubiquity of IoT(the Internet of Things), the demand for high capacity, non-relay, and ultra-long-haul transmission of power communication systems would be greatly increased. By using highorder Raman amplification technology, enhanced high-concentration remote pump amplification technology,multi-bypass long-distance pumping technology and coherent optical transmission technology, an ultralong-distance non-relay optical transmission system is built up with a large effective area G.654.E optical fiber as the transmission medium. And the 2.5 G SDH 726 km and 10 G SDH 681 km non-relay transmission is realized, which is the longest transmission distance achieved by 2.5 G and 10 G systems in the current literature. The experimental results provide experimental basis and reference for evaluating the performance and indicators of large-capacity and ultra-long-range non-relay transmission system.
