摘要
近年来,随着能源互联网与电力物联网的快速发展,国家电网有限公司各业务系统对通信系统传输带宽要求越来越大,2013年建成的单波10 G大容量骨干光传输系统(Optical Transport Network,OTN)已无法满足未来几年的需求。目前单波100 G OTN系统技术日趋成熟,但10 G/100 G的混传测试与应用较少,文章介绍了10 G/100 G混传过程中遇到的技术问题,并通过实验测试和数据分析,得出了相关结论和解决方案,对后续国家电网有限公司大容量骨干光传输系统从单波10 G网络向单波100 G网络平滑升级具有重要的参考价值。
In recent years, Energy Internet and the electric Internet of Things make great progress, the developing information systems bring huge bandwidth requirement in transmission system of SGCC, the 10 G OTN transmission system which was built in 2013 cannot satisfy the demand in the future. The 100 G OTN transmission system has good performance and high quality now, but experiments and applications with 10 G and 100 G hybrid transmission system are rare. This paper introduces the technical problems encountered in the process of 10 G and 100 G hybrid transmission, and draws the relevant conclusions and solutions through experimental test and data analysis. It has important reference value for the subsequent smooth upgrade of OTN from single wave 10 G network to single wave 100 G network in SGCC.
