Transmitting and receiving equipment for radiocommunication - Frequency response of optical-to-electric conversion device in high-frequency radio-over-fibre systems - Part 2: Measurement method of common-mode rejection ratio of optical coherent detection device for radio-over-fibre transmitter

Apstrakt

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.
