光放大器. 试验方法. 第3-3部分: 噪声指数参数. 信号功率与总ASE功率比

[中文适用范围]： 本部分IEC 61290-3适用于所有商业可用的单通道光放大器（OA），包括使用光泵浦光纤（OFA）的光放大器（基于掺稀土光纤或拉曼效应）、半导体光放大器模块（SOA模块）和平面光波导放大器（POWA）。更具体地说，它适用于放置在光接收器之前的单通道OA，且在OA与接收器之间没有放置光学带通滤波元件。本部分IEC 61290-3的目的是建立统一要求，以准确可靠地测量OA在接收器光带宽内产生的信号输出功率与总放大自发辐射（ASE）功率之比。该量是接收器处自发-自发拍频噪声的度量，并与IEC 61290-3和IEC 61291-1中定义的OA的自发-自发噪声因子F sp-sp相关。IEC 61290-3-1描述了使用光学频谱分析仪（OSA）测量信号-自发噪声因子F sig-sp的方法，但未描述测量F sp-sp的方法。IEC 61290-3-2描述了使用电频谱分析仪（ESA）测量总噪声因子F sp-sp + F sig-sp的方法。然而，该方法无法单独测量F sp-sp，因此无法直接量化接收器处自发-自发拍频噪声的影响。本部分IEC 61290-3补充了IEC 61290-3-1和IEC 61290-3-2，因为它提供了这种手段。该部分提供了两种测量信号输出功率与总ASE功率之比的方法。第一种方法使用OSA，第二种方法使用带通滤波器和光功率计。 [外文原描述]： 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
