IEC 61300-3-7:20 21描述了可用于测量双端口单模无源光学元件的衰减和回波损耗的波长依赖性的方法。然而，它不适用于密集波分复用(DWDM)设备。IEC 61300-3-29中描述了DWDM器件衰减的波长依赖性的测量方法。本文档中描述了两个测量案例:仅测量衰减；同时测量衰减和回波损耗。这第三版取消并取代了2009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:减少提议引入的替代方法的数量-符合行业惯例；使用行业中更常见的对数形式重新陈述插入损耗和回波损耗方程；关于创建光纤终端的附加建议；对本文件中使用的光源的表征的附加讨论；双向测试的简化；取消单独的仅回波损耗测量程序。

IEC 61300-3-7:2021 describes methods available to measure the wavelength dependence of attenuation and return loss of two-port, single mode passive optical components. It is not, however, applicable to dense wavelength division multiplexing (DWDM) devices. Measurement methods of wavelength dependence of attenuation of DWDM devices are described in IEC 61300-3-29.There are two measurement cases described in this document:

1. measurement of attenuation only;
2. measurement of attenuation and return loss at the same time.

This third edition cancels and replaces the second edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

1. reduction of the number of alternative methods proposed to bring in-line with industry practice;
2. re-statement of the equations for insertion loss and return loss using logarithmic forms more common in the industry;
3. additional recommendations with respect to the creation of fibre terminations;
4. additional discussion on the characterization of the optical sources used in this document;
5. simplification of bi-directional testing;
6. removal of separate return loss only measurement procedures.
