适用于商用光放大器（OA），如IEC 61292-3中分类的光纤放大器（OFA）、半导体光放大器（SOA）和平面波导放大器（PWOA）。其目的是通过光谱分析仪（OSA）试验方法，建立准确可靠测量IEC 61291-1中定义的以下OA参数的统一要求:a）信号自发噪声系数；b） 正向放大自发辐射（ASE）功率级。 IEC 61290本部分概述的方法仅适用于单通道刺激。

Applies to commercially available optical amplifiers (OAs) such as optical fibre amplifiers (OFAs), semiconductor optical amplifiers (SOAs) and planar wageguide apmlifiers (PWOAs) as classified in IEC 61292-3.The object is to establish uniform requirements for accurate and reliable measurements, by means of optical spectrum analyzer (OSA) test method, of the following OA parameters, as defined in IEC 61291-1: a) signal-spontaneous noise figure; b) forward amplified spontaneous emission (ASE) power level. The methods outlined in this part of IEC 61290 apply to single-channel stimulus only.
