标准摘要
[中文适用范围]： IEC 61282@ 这一部分是一份技术报告@，其目的是提供带内光信噪比 (OSNR) 的定义，该定义适用于频谱噪声功率密度不独立于光信噪比的情况。光频率@如IEC 61280-2-9@的OSNR定义中假设的那样，但在信号的光带宽上显着成形。考虑到针对不同用例开发多种测量方法@如下详述@，最好建立一个独立于所使用方法的带内 OSNR 定义，并且@此外@与 IEC 61280-2 的 OSNR 定义一致-9 在与频率无关的噪声功率密度的情况下。 [外文原描述]： IEC TR 61282-12:2016(E), which is a Technical Report, provides a definition for in-band optical signal-to-noise ratio (OSNR) that is applicable to situations where the spectral noise power density is not independent of the optical frequency, as assumed in the OSNR definition of IEC 61280-2-9, but is significantly shaped across the optical bandwidth of the signal. Considering the development of multiple measurement methods for different use cases, as detailed in this Technical Report, it is desirable to establish a definition of in-band OSNR that is independent of the method used and, furthermore, is consistent with the OSNR definition of IEC 61280-2-9 in the case of frequency-independent noise power density. Keywords: in-band optical signal-to-noise ratio (OSNR)
