In this paper we have theoretically shown that two-part and three-part multihelicoidal fibers of heterogeneous type in the presence of twist defects are able to invert the topological charge of incoming optical vortices. We have shown that three-part multihelicoidal fibers of that type can be used as compact comb filters for optical vortices. Also we have studied the emergence of topologically charged fields localized near defects in such fibers. We have established that strongly localized fields can emerge only in three-part multihelicoidal fibers.
