IEC 61290-4-4:20 18适用于光放大器（OA）和光放大的基本子系统。更具体地，它适用于使用含有稀土掺杂剂的有源光纤(光纤放大器，OFAs)的OAs，例如目前可商购的掺铒光纤放大器(EDFA)，如IEC 61291-1中所示。本文档提供了光放大器增益瞬态及其测量的一般背景，并指出了用于准确可靠地测量以下瞬态参数的IEC标准测试方法:a)光输入功率增加/减少瞬态增益过冲和瞬态净增益过冲；b)光输入功率增加/减少瞬态增益下冲和瞬态净增益下冲；c)光输入功率增加/减少增益偏移；d)光输入功率增加/减少瞬态增益响应常数(建立时间)。这些参数已经被包括在内，以提供增益控制OA的瞬态行为的完整描述。如果放大器是OFA或替代类型的OA，此处定义的参数是适用的。关键词:光放大器（OAs）增益瞬态

IEC 61290-4-4:2018 applies to optical amplifiers (OAs) and optically amplified elementary sub-systems. More specifically, it applies to OAs using active fibres (optical fibre amplifiers, OFAs) containing rare-earth dopants, such as erbium doped fibre amplifiers (EDFAs), presently commercially available, as indicated in IEC 61291-1. This document provides the general background for optical amplifier gain transients and their measurements and indicates those IEC standard test methods for accurate and reliable measurements of the following transient parameters:
a) optical input power increase/decrease transient gain overshoot and transient net gain overshoot;
b) optical input power increase/decrease transient gain undershoot and transient net gain undershoot;
c) optical input power increase/decrease gain offset;
d) optical input power increase/decrease transient gain response constant (settling time).
These parameters have been included to provide a complete description of the transient behaviour of gain controlled OA. The parameters defined here are applicable if the amplifier is an OFA or an alternative type of OA.
