This part of IEC 62803 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.
