The radiation spectrum, reflected from the Bragg gratings of different length in spun-fiber were investigated. It is shown that if the grating length much less than the fiber spin pitch there is a wavelength shift of a spectrum depending on input polarization state. This shift decreases with increase of grating length. The theoretical model describing this dependence is developed.
