IEC 61290-3-3:2013适用于所有商用单通道光放大器（OA），包括使用基于稀土掺杂光纤或拉曼效应的光泵光纤（OFA）、半导体光放大器模块（SOA模块）和平面光波导放大器（POWA）的OA。更具体地说，它适用于放置在光学接收器之前的单通道OA，其中OA和接收器之间没有放置光学带通滤波元件。IEC 61290-3本部分的目的是为准确可靠地测量接收器光带宽中信号输出功率与OA产生的ASE总功率之比制定统一要求。这个量是接收器处自发拍频噪声的量度，与OA、Fsp的自发噪声因子相关- sp，定义见IEC 61290-3和IEC 61291-1。 关键词:单通道光放大器（OA）、半导体光放大器模块（SOA模块）、平面光波导放大器（POWA）、接收机光带宽中信号输出功率与OA产生的ASE总功率之比的测量

IEC 61290-3-3:2013 applies to all commercially available single channel optical amplifiers (OAs), including OAs using optically pumped fibres (OFAs) based on either rare-earth doped fibres or on the Raman effect, semiconductor optical amplifier modules (SOA modules) and planar optical waveguide amplifiers (POWAs). More specifically, it applies to single channel OAs placed before optical receivers, where there are no optical bandpass filtering elements placed between the OA and the receiver. The object of this part of IEC 61290-3 is to establish uniform requirements for accurate and reliable measurement of the ratio of the signal output power to the total ASE power generated by the OA in the optical bandwidth of the receiver. This quantity is a measure of the spontaneous-spontaneous beat noise at the receiver, and is correlated to the spontaneous-spontaneous noise factor of the OA, Fsp-sp, as defined in IEC 61290-3 and IEC 61291-1. Keywords: single channel optical amplifiers (OAs), semiconductor optical amplifier modules (SOA modules), planar optical waveguide amplifiers (POWAs), measurement of the ratio of the signal output power to the total ASE power generated by the OA in the optical bandwidth of the receiver
