摘要
随着技术的发展,电力系统普遍应用的10 Gb/s波分复用系统(wavelength division multiplexing,WDM)/光传送网(optical tlansmission net,OTN)技术可能面临着更新换代,为探索100 Gb/s WDM/OTN在电力应用中存在的问题,分析100 Gb/s WDM/OTN技术的标准成熟情况、与40 Gb/s技术的比较、100 Gb/s技术的特点、在电力可能应用的场景、光纤、站距的选择,以及设备、保护方式、接口的选择及网络管理和维护等,指出100 Gb/s技术和标准已经成熟,电力系统应跳过40 Gb/s阶段直接采用100 Gb/s技术,电力系统现有光纤、站距基本可满足100 Gb/s应用要求,设备选择宜采用电交叉类型等。
As technology progresses, the technology of 10 Gb/s wavelength division multiplexing（WDM）/optical transmission network（OTN） applied widely in the electric power system may be upgraded and replaced. To study the problem existing in the application of 100 Gb/s WDM/OTN in power system, the article analyzed the standard maturity of 100 Gb/s WDM/OTN, the characteristics of 100 Gb/s and the comparison between 40 Gb/s and 100 Gb/s. The possible application scene is researched, and the selection of optical fiber, hop, equipments, protection way and interface, and network management and maintenance are also analyzed. It is put forward that the technology and codes of 100 Gb/s are mature, and 100 Gb/s should be used rather than 40 Gb/s in power system. It concludes that the optical fiber and hop of electric power system can meet the requirement of 100 Gb/s, and the electronic cross-connection equipment should be the preferable selection.
