标准摘要
[中文适用范围]： 提供了一种参数定义和测试方法，用于使用在多通道接口处测量光谱的设备来获得光信噪比 (OSNR)。测量的噪声不包括源相对强度噪声 (RIN) 或 [外文原描述]： Provides a parameter definition and test method for obtaining optical signal-to-noise ratio (OSNR) using apparatus that measure the optical spectrum at a multichannel interface. The measured noise does not include source relative intensity noise (RIN) or receiver noise. Three implementations for an OSA are discussed: a diffraction-grating-based OSA, a Michelson interferometer-based OSA, and a Fabry-Perot-based OSA. Characteristics of the OSA that affect OSNR measurement accuracy are provided.
