[中文适用范围]： 本部分适用于所有商用光放大器（OA）和光放大子系统。适用于使用光泵浦光纤（基于稀土掺杂光纤或拉曼效应的光纤放大器）、半导体（半导体光放大器）和平面光波导（平面光波导放大器）的光放大器。本文件不适用于保偏光放大器。本文件定义了通过电频谱分析仪测试方法，对IEC 61291-1第3条定义的以下OA参数进行准确可靠测量的统一要求：a) 标称输出信号功率；b) 增益；c) 反向增益；d) 最大增益；e) 偏振相关增益。此外，本测试方法提供了测量以下参数的手段：- 最大增益波长；- 增益波长带。本文件专门涵盖单通道放大器。对于多通道放大器，适用IEC 61290-10系列。注1：本文件中描述的测试方法对分布式拉曼放大器的适用性有待进一步研究。注2：保偏光放大器的测试方法有待进一步研究。 [外文原描述]： IEC 61290-1-2:2026 applies to all commercially available optical amplifiers (OAs) and optically amplified sub-systems. It applies to OAs using optically pumped fibres (OFAs based on either rare-earth doped fibres or on the Raman effect), semiconductors (SOAs), and planar optical waveguides (POWAs). This document does not apply to polarization-maintaining optical amplifiers. This document defines uniform requirements for accurate and reliable measurements, by means of the electrical spectrum analyzer test method, of the following OA parameters, as defined in IEC 61291-1, Clause 3: a) nominal output signal power; b) gain; c) reverse gain; d) maximum gain; e) polarization-dependent gain. In addition, this test method provides a means for measuring the following parameters: - maximum gain wavelength; - gain wavelength band. This document specifically covers single-channel amplifiers. For multichannel amplifiers, the IEC 61290-10 series applies. NOTE 1 The applicability of the test methods described in this document to distributed Raman amplifiers is for further study. NOTE 2 A test method for polarization-maintaining optical amplifiers is for further study. This third edition cancels and replaces the second edition published in 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of information on the applicability of this document to the scope; b) harmonization of the scope with the IEC 61290-1 series; c) addition of safety recommendations to Clause 4 and Clause 5; d) correction of an error in Clause 7, item e); e) replacement of the term "wavelength measurement accuracy" with "wavelength accuracy".
