光放大器.试验方法.第1部分:功率和增益参数

[中文适用范围]： 本部分IEC 61290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(OFA))、半导体(半导体光放大器(SOA))和波导(平面光波导放大器(POWA))的光放大器。本文件特别针对单通道放大器。多通道放大器的测试方法在IEC 61290-10系列中定义。本文件建立了对以下OA参数进行准确可靠测量的统一要求，如IEC 61291-1:2018第3条所定义：a)标称输出信号功率；b)增益；c)反向增益；d)最大增益；e)最大增益波长；f)增益随温度的最大变化；g)增益波长带；h)增益波长变化；i)增益稳定性；j)偏振相关增益；k)增益纹波(仅SOA)；l)大信号输出稳定性；m)饱和输出功率；n)最大输出信号功率；o)最大总输出功率。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仍在研究中。注2：所有带有(‡)的数值是建议值，保证测量的准确性。其他值在验证后可接受。 [外文原描述]： IEC 61290-1:2022 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61290-1:2022 applies to all commercially available optical amplifiers (OAs) and optically amplified subsystems. It applies to OAs using optically pumped fibres (optical fibre amplifiers (OFAs) based on either rare-earth doped fibres or on the Raman effect), semiconductors (semiconductor optical amplifiers (SOAs)), and aveguides (planar optical waveguide amplifiers (POWAs)). It is specifically directed to single-channel amplifiers. Test methods for multichannel amplifiers are defined in the IEC 61290-10 series. This document establishes uniform requirements for accurate and reliable measurements of the following OA parameters, as defined in IEC 61291-1:2018, Clause 3: a) nominal output signal power; b) gain; c) reverse gain; d) maximum gain; e) maximum gain wavelength; f) maximum gain variation with temperature; g) gain wavelength band; h) gain wavelength variation; i) gain stability; j) polarization-dependent gain; k) gain ripple (SOA only); l) large-signal output stability; m) saturation output power; n) maximum output signal power; o) maximum total output power. NOTE 1 The applicability of the test methods described in this document to distributed Raman amplifiers is still under study. NOTE 2 All numerical values followed by (‡) are suggested values for which the measurement is assured. Other values are acceptable if verified. This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - specification of gain ripple as a new parameter; - specification of test method and test report for gain ripple measurements; - use of the term “measurement uncertainty” instead of “measurement accuracy”.
