The delay distortion characteristics of optical fiber splices are evaluated. Two 1.35-km graded index fibers with different transmission characteristics were each bisected and spliced together to determine how longitudinal and transverse displacement of fibers in a splice affect the delay distortion characteristics of a transmission path. The transmission characteristics of both the optical source and the fibers used play an important role in determining how delay distortion is affected by splice misalignment. The first fiber exhibited a great deal of mode mixing and a very small increase in delay distortion as the fibers were offset in the splice. In contrast, the second fiber exhibited very little mode mixing, but increased markedly in delay distortion as the fibers in the splice were displaced.
对光纤熔接的延迟失真特性进行了评估。将两根具有不同传输特性的1.35公里渐变折射率光纤分别对半切开并拼接在一起，以确定熔接处光纤的纵向和横向位移如何影响传输路径的延迟失真特性。所使用的光源和光纤的传输特性在确定熔接不对准如何影响延迟失真方面都起着重要作用。第一根光纤表现出大量的模式混合，并且当光纤在熔接处偏移时，延迟失真的增加非常小。相比之下，第二根光纤表现出很少的模式混合，但随着熔接处光纤的位移，延迟失真显著增加。
