Optical signals transmitted through cladded glass fibers are subject to delay distortion because of (1) dispersion in the material, (2) dispersion caused by the waveguide characteristic, and (3) delay differences between modes. We isolate these effects and evaluate their significance for cases of practical interest. These concern fibers in which the refractive index of the cladding is only slightly lower than that of the core.
通过包层玻璃纤维传输的光信号会受到延迟失真的影响，原因如下：(1) 材料中的色散；(2) 波导特性引起的色散；(3) 模式之间的延迟差异。我们将这些影响因素分离出来，并评估它们在实际感兴趣的情况下的重要性。这些情况涉及包层折射率仅略低于纤芯折射率的光纤。
