| 摘 要： | 本文测量了100,130,150和180℃下、1atm氢气氛中的MCVD多模光纤损耗谱的变化。研究了分子氢和氢氧根分别在1.24μm,1.41μm引起的损耗增加,由实验结果推出损耗增加与时间、温度关系的经验公式,估算了室温下(20℃)20年后1.3μm,1.55μm的损耗增加。关键词：

| Abstract: | Spectrum attenuation changes for MCVD optical fiber exposed to a hydrogen atmosphere at 100, 130, 150 and 180℃ are measured. The loss increases at 1.24 μm and 1.41μm due to molecular hydrogen and hydroxyl respectively are investigated. The empirical formula for time and temperature dependence of the loss increase are obtained from the experimental results. The loss increase at 1.3 μm and 1.55μm, at room temperature are estimated. |
