We analyze formation of multifocus structure during the propagation of optical vortex with topological charge m = 1 in fused silica at wavelength 1800 nm, which corresponds to region of anomalous group velocity dispersion. Propagation of pulse is accompanied by sequence of nonlinear focuses, where each focus is a high intensive ring.
