IEC 61290-4-1:20 16适用于使用含有稀土掺杂剂的有源光纤（光纤放大器（OFAs））的光放大器（OAs），包括掺铒光纤放大器（EDFAs）和光放大基本子系统。这些放大器是商业上可获得的，并且广泛部署在服务提供商网络中。文件的目的是提供OFA瞬态和相关参数的一般背景，并描述准确可靠测量以下瞬态参数的标准测试方法: -通道添加或移除瞬态增益过冲和瞬态净增益过冲； -信道添加或移除瞬态增益下冲和瞬态净增益下冲； -信道添加或移除增益偏移； -通道添加或移除瞬态增益响应时间常数(建立时间)。第二版取消并取代了2011年出版的第一版。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: -将适用范围从仅EDFA扩展到所有OFA； -更新了定义，以便与IEC 61290-4系列中的其他文件保持一致。 关键词:光放大器(OAs),光纤放大器(OFAs),稀土掺杂剂,掺铒光纤放大器

IEC 61290-4-1:2016 applies to optical amplifiers (OAs) using active fibres (optical fibre amplifiers (OFAs)) containing rare-earth dopants including erbium-doped fibre amplifiers (EDFAs) and optically amplified elementary sub-systems. These amplifiers are commercially available and widely deployed in service provider networks. The object of document is to provide the general background for OFA transients and related parameters, and to describe a standard test method for accurate and reliable measurement of the following transient parameters:
- channel addition or removal transient gain overshoot and transient net gain overshoot;
- channel addition or removal transient gain undershoot and transient net gain undershoot;
- channel addition or removal gain offset;
- channel addition or removal transient gain response time constant (settling time). This second edition cancels and replaces the first edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- extended the applicability from only EDFAs to all OFAs;
- updated definitions for consistency with other documents in the IEC 61290-4 series. Keywords: optical amplifiers (OAs), optical fibre amplifiers (OFAs), rare-earth dopants, erbium-doped fibre amplifiers
