| 摘 要： | 大芯径石英阶跃光纤的谱损耗是光纤传输性能的重要参数之一。介绍了大芯径光纤光谱衰减的测量方法,对大芯径阶跃光纤在400～600nm光谱范围内的谱损耗特性进行了研究。结果表明,光纤在400～600 nm范围内的谱损耗随波长的减小而增大,通过实测得到的600nm处的损耗系数为12 dB/km,400nm处的光谱损耗系数为96dB/km。

| Abstract: | Spectrum loss of large-core step-index pure SiO2 fiber is one of the important parameter.Experimental method and system are established for the measurement of attenuation spectrum of large-core optical fiber at 400～600 nm.Results show that the shorter wavelength is,the larger the loss is,loss value is 11 dB/km at 600 nm,and is 96 dB/km at 400 nm. |
