Overview
IEC 62803:2016 is an international standard published by the International Electrotechnical Commission (IEC) that specifies a measurement method for the frequency response of optical-to-electric (O/E) conversion devices used in high-frequency radio over fibre (RoF) systems. This standard addresses the critical need to accurately evaluate components such as photodiodes and difference-frequency generation (DFG) devices that convert optical signals into electrical signals for wireless communication and broadcasting.
Covering a broad frequency range up to 100 GHz (practically up to 110 GHz) and operating across optical wavelengths between 0.8 µm and 2.0 µm, IEC 62803:2016 provides essential guidelines to ensure reliable and consistent measurement of device performance in cutting-edge radiocommunication technologies.
