FIELD: radio engineering, communication.
SUBSTANCE: apparatus has a dielectric waveguide in form of a hollow cylinder with openings in the wall for inlet of fibre-optic links lying at a distance δ from each other. Leads of the fibre-optic links are placed in a cylinder bushing made of waveguide material. The bushing is tightly fit into the cavity of the waveguide and protrudes from the waveguide by a distance h. An optical lens is placed coaxially opposite the bushing. The distances δ and h are selected to be comparable with the given wavelength λ of radio-frequency radiation. To ensure coaxiality of the fibre-optic link and the optical axis of the lens, the waveguide is placed such that coaxiality can be adjusted. To protect information radio-wave radiation from spurious reflection, the waveguide is placed in a pipe made of porous dielectric material with low permittivity.
EFFECT: invention improvement.
