对可见光和近红外波段内光纤的损耗进行了实验研究。采用光纤截断法对多色光在光纤传输过程的损耗进行了实验测量,得到了光纤在可见光波段内吸收系数对波长的变化关系。对在500nm到1000nm的波段内存在的多处光纤吸收峰值给出了相应的解释。
The loss of optical fiber in the visible and near infrared bands was experimentally studied. The optical fiber truncation method was used to measure the loss of multi-color light in the process of optical fiber transmission. The relationship between the absorption coefficient and the wavelength of the optical fiber in the visible light band was obtained. Corresponding explanations are given for the absorption peaks of a plurality of optical fibers existing in the wavelength band of 500 nm to 1000 nm.
