标准范围

IEC 61300-3-35:2022涉及碎片、划痕和缺陷的观察和分类。检验要求基于IEC TR 62627-05。IEC TR 62627-01中提供了清洁光纤/套圈污染物的建议，附录D中给出了建议。IEC TR 62572-4提供了光收发器短截线的清洁方法。目视检查是对诸如衰减和回波损耗或端面参数的性能参数的测量的补充，而不是替代。选择指定的尺寸，使得它们可以容易地估计。不仅要检查光纤上的A区和B区是否有缺陷和划痕，而且还需要检查整个接触区域(两个光纤/套圈在配合时相遇的地方)是否有污染(对于圆柱形套圈，直径高达250 μ m，对于矩形套圈，整个套圈表面)。本文件的目标如下:-规定显微镜符合本文件的最低标准；-规定检查光纤端面清洁度的程序和标准，以确定端面是否适合使用。所有连接器光学接口（IEC 61755系列和IEC 63267系列）都基于光纤芯之间的物理接触；-为端面图像的分析提供定量标准。这第三版取消并取代了2015年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:-增加了目视检查不能替代诸如衰减和回波损耗测量等光学鉴定的声明；-增加一些术语和定义；-增加了对SM 35 dB连接器的要求；-在第5条中增加关于方法对系统可变性和来自同一供应商的系统内可变性的敏感性的句子；-取消对C区和D区的检查要求；-插入整个矩形套圈和每根光纤周围250 μ m区域的通用清洁度规范；-添加矩形和圆柱形套圈的清洁建议；-检查区B的外边缘从115 μ m变为110 μ m，以满足显微镜固定装置的制造公差；-更改部分位于堆芯中的缺陷仅针对其位于堆芯中的部分进行判断。缺陷的其余部分被认为位于包层中。-增加了不能仅因目视检查不合格而拒绝连接器的声明。满足规定的光学性能决定了该连接器的使用。

IEC 61300-3-35:2022 is concerned with the observation and classification of debris, scratches and defects. The inspection requirements are based on IEC TR 62627-05. Advice for cleaning of contamination from fibres/ferrule is found in IEC TR 62627-01 and a recommendation is given in Annex D. IEC TR 62572-4 provides the cleaning method for a stub for optical transceivers. Visual inspection is in addition to, and does not replace measurement of performance parameters such as attenuation and return loss, or end face parameters. The dimensions specified are chosen such that they can be easily estimated. Not only the zones A and B on the fibre are inspected for defects and scratches but the whole contact area (where the two fibres/ferrules meet when mated) needs to be inspected for contamination (this is up to 250 μm diameter for cylindrical ferrules and the whole ferrule surface for rectangular ferrules).The objectives of this document are the following:
- specify the minimum criteria for a microscope to be compliant to this document;
- specify the procedure and criteria for inspecting fibre-optic end faces for cleanliness to determine if the end faces are fit for use. All connector optical interfaces (IEC 61755 series and IEC 63267 series) are based on physical contact between fibre cores;
- provide quantitative criteria for the analysis of end face images.
This third edition cancels and replaces the second edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- adding of a statement that visual inspection is not a substitute for optical qualification such as attenuation and return loss measurement;
- adding of some terms and definitions;
- adding requirements for SM 35 dB connectors;
- adding of a sentence in Clause 5 concerning the susceptibility of the methods to system variability and variability within systems from same supplier;
- removal of inspection requirements for zones C and D;
- insertion of a generic cleanliness specification for whole rectangular ferrule and 250 μm area around every fibre;
- adding a cleaning recommendation for rectangular and cylindrical ferrules;
- outer edge of inspection zone B has changed from 115 μm to 110 μm to meet manufacturing tolerances of fixture for microscopes;
- change that defects that are partly in core are only to be judged for the part they are in the core. The remainder of the defect is considered to be located in the cladding.
- adding a statement that a connector cannot be rejected by just failing visual inspection. Meeting the specified optical performance determines the use of this connector.
