摘　　要：用 OTDR测试光纤线路时 ,其背向瑞利散射信号曲线上常出现幻峰。There may be unreal peaks on backscattering signal curve in the measurement of optical fiber links by OTDR. This paper gives a quantitative analysis of the causes for the occurrence of unreal peaks and describes in brief the effect of unreal peaks on the measurement, the identification and elimination of unreal peaks.

关 键 词：光缆 瑞利散射 背向散射曲线
