纤维光学互连器件和无源元件. 基本试验和测量程序. 第3-35部分: 检查和测量. 纤维光学连接器和纤维桩收发器的目视检查

[中文适用范围]： IEC 61300 的这一部分描述了使用光纤插芯类型接口定量评估抛光光纤连接器或光纤收发器端面质量的方法。本标准不考虑次表面裂纹和断裂。一般来说，本标准中描述的方法适用于包含在插芯内的 125 μm 包层光纤，并且旨在与 2 W 输入功率源一起使用。然而，部分适用于非套圈连接器和其他光纤类型。在适当的地方识别这些部分。本标准的目的并不是测量划痕的大小，而是选择可以估计的尺寸和要求。例如，如果划痕宽度为 2.3 μm，则无需测量。 [外文原描述]： IEC 61300-3-35:2015 describes methods for quantitatively assessing the end face quality of a polished fibre optic connector or of a fibre optic transceiver using a fibre-stub type interface. Sub-surface cracks and fractures are not considered in this standard. In general, the methods described in this standard apply to 125 μ cladding fibres contained within a ferrule and intended for use with sources of ≤ 2 W of input power. However, portions are applicable to non-ferruled connectors and other fibre types. Those portions are identified where appropriate. It is not the intention of this standard that the size of scratches should be measured, the dimensions and requirements are selected such that they can be estimated. There is no need to measure for example if a scratch is 2,3 μm wide. This second edition cancels and replaces the first edition published in 2009 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - modification to the title; - addition of some terms and definitions; - reconsideration of the specific values of Tables 1 to 4 to reflect the current market situation; - addition of visual requirements for single-mode transceivers using a fibre-stub interface in Table 3; - addition of a sentence in 4.1 concerning the susceptibility of the methods to system variability. Keywords: end face quality of a polished fibre optic connector, fibre optic transceiver using a fibre-stub type interface
