N2 - Brillouin dynamic gratings (BDGs) have been usually created in polarization maintaining fibers (PMFs). In this study, we use conventional single-mode fibers (SMFs) which are coiled with care. In addition, we derive approximations of the BDG properties based on the moving fiber Bragg grating (FBG) model. We find the experiments agree well with the calculations in terms of fundamental BDG properties: frequency offset, reflectance, bandwidth. Our results therefore reinforce the previous reports on the BDGs in which the agreement between calculations and experiments was not satisfactory. Furthermore, our results suggest the possibility of locating bent fibers with high sensitivity.
