标准摘要
[中文适用范围]: 本国际标准适用于光纤滤波器系列。这些组件具有以下所有一般特征: – 它们是无源的,因为它们不包含可以处理发射到输入端口的光信号的光电或其他转换元件; – 它们改变光谱强度分布以选择某些波长并抑制其他波长; – 它们是固定的,即光谱强度分布的修改是固定的并且无法调谐; – 具有输入和输出端口或公共端口(具有输入和输出功能),用于传输光功率;所述端口为光纤或光纤连接器; – 它们根据各自的特点而有所不同。它们可以分为以下几类: ?短波通(仅允许低于或等于规定值的波长通过); ?长波通(仅允许大于或等于指定值的波长通过); ?带通(仅允许光学窗口); ?凹口(仅光学窗口被抑制)。也可以将上述类别组合起来。 [外文原描述]: IEC 61977:2010(E) applies to the family of fibre optic filters. These are passive components used to select specific wavelengths. The standard covers their optical, mechanical and envoronmental properties; as well as the measurement and text procedures for quality assessment. The changes with respect to the previous edition include having substantially increased the number of terms, added an informative annex for example of filtering technologies and deleted quality assessment procedures.
