Water-blocking homing optical fiber composite bunched cable and preparation method thereof

The invention relates to the technical field of cables, in particular to a water-blocking homing optical fiber composite bunched cable and a preparation method thereof. The water-blocking homing optical fiber composite bunched cable comprises an optical fiber, a first cable, a second cable, a third cable and a fourth cable. The optical fiber and the first cable are connected through a vertical connecting rib. The first cable and the second cable are connected through a vertical connecting rib. The second cable and the third cable are connected through a transverse connecting rib. The third cable and the fourth cable are connected through a vertical connecting rib. The transverse connecting rib and the vertical connecting rib are each provided with an oval long-strip-shaped open hole. The first cable, the second cable, the third cable and the fourth cable each comprise an insulating layer, a plurality of conductive units and a water blocking tape. Water blocking yarns are arranged between the plurality of cond
