Abstract
A ferrule for optical connector has a body in which lines of fiber holes are arranged in a plurality of tiers. A cavity is formed in the body, and its bottom connects with the respective inlets of the fiber holes. The bottom of the cavity is a tiered bottom designed so that the respective inlet positions of the fiber holes are differentiated in stages between adjacent lines of the fiber hole array. The tiered bottom is formed having guide grooves that extend toward the respective inlets of the fiber holes in the same column of the fiber hole array. An opening is formed in a position of the outer surface of the body parallel to rows of the fiber hole array. The opening allows the tiered bottom to be exposed through the outer surface of the body.
