The orbit of the spectroscopic binary system HD107346 is calculated from 50 CORAVEL-type radial velocity measurements. An orbit with a period P = 1024.2 days is obtained. The spectral type of the primary, G8IV, has been estimated from the spectrum analyzed by Straizys (1984). The spectral type and absolute magnitude of the secondary, sdO, is estimated by modeling the spectral energy distribution of the binary constructed from measurements in the FAUST, GALEX, UBV, Vilnius, I Cousins and JHK photometric systems. The subdwarf component of the binary system exhibits a very high temperature. We do not exclude that the hot component is a close interacting binary.
