IEC 61290-1-3:20 21 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 61290-1-3:20 21适用于所有市售光放大器（OA）和光放大子系统。它适用于使用光泵浦光纤（基于稀土掺杂光纤或拉曼效应的OFA）、半导体（SOA）和波导（POWA）的OA。 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。本文件的目的是为通过光功率计测试方法准确可靠地测量IEC 61291中定义的下列OA参数建立统一要求-1: -标称输出信号功率； -增益； -偏振相关增益； -最大输出信号功率； -最大总输出功率。 注2所有后跟（？）的数值均为建议值，可保证测量结果。在验证后，其他值可以是可接受的。 本文档适用于单通道放大器。对于多通道放大器， IEC 61290-10（所有部件）适用。这第四版取消并取代了2015年出版的第三版。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: -与IEC 61290-1-1协调； -使用术语“测量不确定度”而不是“测量准确度”。

IEC 61290-1-3:2021 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 61290-1-3:2021 applies to all commercially available optical amplifiers (OA) and optically amplified subsystems. It applies to OA using optically pumped fibres (OFA based on either rare-earth doped fibres or on the Raman effect), semiconductors (SOA), and waveguides (POWA).
NOTE 1 The applicability of the test methods described in this document to distributed Raman amplifiers is for further study. The object of this document is to establish uniform requirements for accurate and reliable measurements, by means of the optical power meter test method, of the following OA parameters, as defined in IEC 61291-1:
- nominal output signal power;
- gain;
- polarization-dependent gain;
- maximum output signal power;
- maximum total output power.
NOTE 2 All numerical values followed by (？) are suggested values for which the measurement is assured. Other values can be acceptable upon verification.
This document applies to single-channel amplifiers. For multichannel amplifiers,
IEC 61290-10 (all parts) applies. This fourth edition cancels and replaces the third edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- harmonization with IEC 61290-1-1;
- use of the term "measurement uncertainty" instead of "measurement accuracy".
