摘　　要：描述了幻峰及其对OTDR测试光纤线路的影响,重点从理论上分析了OTDR在“最小二乘法”模式下的工 作原理,并对OTDR在“最小二乘法”模式和“两点法”模式下测试光纤接头损耗进行了比较。The paper describes unreal peaks and the effect of them on the measurement of fiber circuit with OTDR. It gives a theoretical analysis of the least square method mode of OTDR, and makes a comparison between of the measurements of fiber splicing loss in the least square method mode and two-point method mode.
