标准摘要
[中文适用范围]: IEC 61290的本部分适用于使用有源光纤的光纤放大器(OFA),含有目前市售的稀土掺杂剂。本国际标准的目的是为准确可靠地测量 IEC 61291—1 中定义的信号自发噪声系数建立统一的要求。该测试方法通过向被测OFA发射光脉冲来独立检测放大信号功率和放大自发辐射(ASE)功率。通过在光脉冲关闭期间同步测量光谱分析仪(OSA)上的功率来测量ASE电平。 .平均光信号电平是通过OSA中的随机采样来测量的。这种测量是可能的,因为稀土掺杂 OFA 的增益响应相对较慢。特别是在掺铒 OFA 中。然而,由于 OFA 增益动态随放大器类型、工作条件和控制方案而变化,因此增益动态应为OFA 制造商应提供验证所需调制频率的数据,以将误差限制在 [外文原描述]: Applies to optical fibre amplifiers (OFA) using active fibres, containing rare-earth dopants, currently commercially available. The object is to establish uniform requirements for accurate and reliable measurements of the signal-spontaneous noise figure as defined in IEC 61291-1.The test method described is, in general, for multichannel applications. Single-channel applications are a special case of multichannel applications. This second edition cancels and replaces the first edition. It is a technical revision with updated references and cautions on proper use of the procedure.
