摘　　要：介绍了500kV官渡变投运时出现的一起长距离SDH光路对接故障。光路两端是不同厂家的设备,对接时一端收光正常而另一端有帧丢失告警。经分析,确认该故障由两端光口工作波长不一致导致。取消故障端预放大器后,对接成功。这起故障的分析处理,为以后不同厂家的组合式光口对接积累了经验。A long-distance optical interconnection failure caused by both ends of disaccord wavelength during 500kV Guandu substation commissioning is introduced.The optical module of each side is made by different company.One side shows a warning signal of 'lost of frame' while the other side receives light successfully.The reason of the failure is analyzed and found that different working wavelength of pre-amplifier at each side leads to the failure.After the pre-amplifier of the failure side is removed,the interconnection is succeeded.The analysis and treatment of the failure has committed experience for subsequent interconnections of combined optical modules made by different companies.
