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…

IEC 62803-3:2024 specifies the measurement method of the non-linear response of optical­to­electric converters in both optical signal transport systems and RoF systems. The method applies for the following: - frequency range: up to 170 GHz; - wavelength band: 0,8 µm to 2,0 µm.

IEC 60335-2-6:2024 deals with the safety of stationary electric cooking appliances, such as cooking ranges, hobs, and ovens, for household use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral, and 480 V for other appliances including direct current (DC) supplied appliances and battery-operated appliances. This standard also…
