标准摘要
[中文适用范围]： IEC 61300-3-7:2021+AMD1:2025 CSV 描述了用于测量双端口单模无源光器件的衰减和回波损耗随波长变化的方法。然而，该标准不适用于密集波分复用（DWDM）器件。DWDM器件的衰减随波长变化的测量方法在IEC 61300-3-29中有详细描述。本文件中描述了两种测量情况：a) 仅测量衰减；b) 同时测量衰减和回波损耗。本版标准取消并替代了2009年发布的第二版，属于技术修订版。与前一版相比，本版做出了以下重大技术修改：a) 减少建议的替代方法数量，以更符合行业实践；b) 使用更常见的对数形式重新表述插入损耗和回波损耗的公式；c) 对光纤端接的制作提供更多建议；d) 对本文件中使用的光学源特性进行更详细的讨论；e) 简化双向测试流程；f) 删除仅测量回波损耗的独立测量步骤。 [外文原描述]： IEC 61300-3-7:2021+AMD1:2025 CSV 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: a) measurement of attenuation only; b) 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: a) reduction of the number of alternative methods proposed to bring in-line with industry practice; b) re-statement of the equations for insertion loss and return loss using logarithmic forms more common in the industry; c) additional recommendations with respect to the creation of fibre terminations; d) additional discussion on the characterization of the optical sources used in this document; e) simplification of bi-directional testing; f) removal of separate return loss only measurement procedures.
