发现纤维带宽光谱和损耗光谱之间存在相似性。与波长有关的远端场辐射图用来推论接近芯中心的高OH离子浓度产生低次模的不同衰减。在水吸收损耗峰值的相同波长处产生了带宽峰。
There is a similarity between the fiber bandwidth spectrum and the loss spectrum. The wavelength-dependent far-field radiation pattern is used to deduce that the concentration of high OH ions near the center of the core produces a different attenuation of the lower order modes. Bandwidth peaks arise at the same wavelength as the peak of water absorption loss.
