标准摘要
[中文适用范围]： IEC 62803-2:2024 规定了高速 RoF 系统以及高速光信号传输系统中光相干检测器件共模抑制比的测量方法。此外，该方法对于估计共模抑制比和 O/E 转换效率的详细频率响应也非常有效。该方法适用于以下情况： - 频率范围：1 GHz 至 110 GHz； - 波长带：0.8 µm 至 2.0 µm。附件 A 中以高速 RoF 系统中光相干检测器件的使用为例。 [外文原描述]： IEC 62803-2:2024 provides the measurement method of the common-mode rejection ratio of optical coherent detection devices in high-speed RoF systems, as well as in high-speed optical signal transmission systems. In addition, the method is also effective for the estimation of the detailed frequency response of the common-mode rejection ratios and O/E conversion efficiency. The method applies for the following: - frequency range: 1 GHz to 110 GHz; - wavelength band: 0,8 µm to 2,0 µm. The use of optical coherent detection devices for high-speed RoF system is shown in Annex A as an example.
