IEC 61291-4:20 11适用于多通道应用中使用的光放大器（OA）器件和子系统。对于单通道应用，请使用IEC 61291-2。该性能规范模板的目的是为准备多通道应用中使用的OA设备和子系统的性能的详细规范提供一个框架。本第三版取消并取代2008年出版的第二版，构成技术修订。主要的显著变化是瞬态参数测试方法IEC 61290-4系列已添加到表1、2和3中。 本出版物应与IEC 61291-1:20 06一起阅读。

IEC 61291-4:2011 applies to optical amplifier (OA) devices and sub-systems to be used in multichannel applications. For single channel applications, use IEC 61291-2. The object of this performance specification template is to provide a frame for the preparation of detail specifications on the performances of OA devices and sub-systems to be used in multichannel applications. This third edition cancels and replaces the second edition published in 2008 and constitutes a technical revision. The main significant changes are the transient parameter test methods, IEC 61290-4 series, have been added to Tables 1, 2, and 3.

This publication is to be read in conjunction with IEC 61291-1:2006.
