光导纤维.第2部分:产品规格.总则

[中文适用范围]： IEC 60793 的这一部分包含多模和单模光纤的通用规范。四个类别多模类别中每个类别的分规范：A1@ A2@ A3@ 和 A4 包含特定于每个类别的要求。两个单模类别@ B 和C @ 中的每一个的分规范都包含每个类别的共同要求。每个分规范都包括系列规范（在规范性附录中），其中包含适用类别或子类别的要求。这些子类别根据不同的光纤类型或应用进行区分。本标准的要求适用于所有类别。每个分规范都包含其内所有系列规范的共同要求。这些通用要求已复制到系列规范中，以便于参考。为每个指定的属性定义测试或测量方法。在可能的情况下，这些定义参考 IEC 标准，否则测试或测量方法将在相关分规范中概述。下表定义了截面规格。相关系列规范在规范性附录的分规范中定义 [外文原描述]： IEC 60793-2:2011 contains the general specifications for both multimode and single-mode optical fibres. Sectional specifications for each of the four categories multimode class: A1, A2, A3, and A4 contain requirements specific to each category. Sectional specifications for each of the two single-mode classes, B and C, contain requirements common to each class. Each sectional specification includes family specifications (in normative annexes) that contain requirements for the applicable category or sub-categories. These sub-categories are distinguished on the basis of different fibre types or applications. The requirements of this standard apply to all classes. This seventh edition cancels and replaces the sixth edition published in 2007. This modification has been necessary because of the addition of new fibre categories to IEC 60793-2-10 and IEC 60793-2-50. This publication is to be read in conjunction with IEC 60793-1 series .
