Faraday effects possibly plays the major role in generation of circular polarization observed on Very Long Base Interferometry scales. Multi-frequency circular polarization measurementrs can become the desired breakthrough in understanding the active galactic nuclei jet physics and the only possibility to estimate some of their vital parameters. We review the possible mechanisms of circular polarization generation and their connection to the jet parameters. We throw a glimpse on the methods of data reduction and finally discuss our current observational progress and its possible interpretation.
