The invention relates to an optical fiber bundle fixing device, a laser conduit thereof and an optical fiber coupling system thereof. The optical fiber bundle fixing device comprises an optical fiber fixing piece and a restraining sleeve, and the restraining sleeve is provided with a taper hole penetrating in the axial direction. The optical fiber fixing piece is arranged in the taper hole, the outer diameter of the optical fiber fixing piece is continuously increased in the axial direction, a through hole penetrating through the axial direction of the optical fiber fixing piece is formed in the optical fiber fixing piece, a plurality of optical fibers penetrate through the through hole, and the optical fiber fixing piece is provided with an expansion joint. And the expansion joint is communicated with the through hole and is used for changing the size of the through hole. The fixing device for mechanically fixing the bundle optical fibers is designed, and various problems caused by the fact that binders are
