本文阐明了单模光纤的最小色散波长同纤芯玻璃和包层玻璃的折射率特性以及同光纤参数矿的依赖关系。用熔融石英和用二氧化锗、三氧化二硼掺杂的熔融石英制作的光纤在1.27微米<λ<1.6微米范围内容易得到最小色散波长,这样,大容量通信系统就可广泛选择工作波长了。 This paper illustrates the dependence of the minimum dispersion wavelength of single-mode fibers on the refractive index properties of core glass and cladding glass and the dependence on optical fiber parameters. Optical fibers made of fused silica and fused silica doped with germanium dioxide, boron oxide, etc. are easy to obtain the minimum dispersion wavelength in the range of 1.27 micrometers <λ <1.6 micrometers so that a wide range of operating systems can be selected for the wide range of communication systems .
