IEC 61290-10-1:20 09适用于使用目前市售的含有稀土掺杂剂的有源光纤的光纤放大器。建立了IEC 61291-1 3.1.18中定义的信号自发噪声系数精确可靠测量的统一要求。该测试方法通过将光脉冲发射到被测OFA中并通过使用光采样开关和光谱分析仪(OSA)同步检测输出脉冲的“开”和“关”电平来独立检测放大信号功率和放大自发辐射(ASE)功率。此版本是一个技术修订版，更新了正确使用该程序的参考文献和注意事项。 本出版物应与IEC 61291-1:20 06一起阅读。

IEC 61290-10-1:2009 applies to optical fibre amplifiers (OFAs) using active fibres, containing rare-earth dopants, currently commercially available. The uniform requirements for accurate and reliable measurements of the signal-spontaneous noise figure as defined in 3.1.18 of IEC 61291-1 are established. The test method independently detects amplified signal power and amplified spontaneous emission (ASE) power by launching optical pulses into the OFA under test and synchronously detecting 'on' and 'off' levels of the output pulses by using an optical sampling switch and an optical spectrum analyzer (OSA). This edition is a technical revision with updated references and cautions on proper use of the procedure.

This publication is to be read in conjunction with IEC 61291-1:2006.
