本文介绍了一种直接测量光纤紫外吸收光谱的新技术，其波长可短至200 nm。在纤维中发现的UV吸收带的形状和强度都对应于在预制件中测量的那些。没有观察到除GeO（240和330 nm）以外的谱带。
A new technique has been developed to measure directly the UV absorption spectrum of optical fibers to wavelengths as short as 200 nm. Both the shape and the intensity of the UV absorption bands found in the fiber correspond to those measured in preforms. No bands other than those attributed to GeO (240 and 330 nm) were observed.
