光纤互连器件和无源元件 - 光纤滤波器 - 通用规范

[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； ?C 它们修改光谱强度分布以选择某些波长并抑制其他波长； ?C 它们是固定的@即光谱强度分布的修改是固定的并且不能调谐； ?C 它们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； ?C 它们根据各自的特点而有所不同。可分为以下几类： 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。该标准规定了以下方面的统一要求： ?C 光学@机械和环境性能。 [外文原描述]： IEC 61977:2015 applies to the family of fibre optic filters. These components have all of the following general features: - they are passive for the reason that they contain no optoelectronic or other transducing elements which can process the optical signal launched into the input port; - they modify the spectral intensity distribution in order to select some wavelengths and inhibit others; - they are fixed, i.e. the modification of the spectral intensity distribution is fixed and cannot be tuned; - they have input and output ports or a common port (having both functions of input and output) for the transmission of optical power; - the ports are optical fibre or optical fibre connectors; - they differ according to their characteristics. They can be divided into the following categories: - short-wave pass (only wavelengths lower than or equal to a specified value are passed); - long-wave pass (only wavelengths greater than or equal to a specified value are passed); - band-pass (only an optical window is allowed); - notch (only an optical window is inhibited). It is also possible to have a combination of the above categories. This standard establishes uniform requirements for the following: optical, mechanical and environmental properties. This third edition cancels and replaces the second edition published in 2010. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - harmonization of a number of terms and definitions with other generic specifications; - deletion of the quality assessment level clause.
