The utility model provides an
optical fiber head adjusting device and an
optical fiber head adjusting
system. The
optical fiber head adjusting device comprises a horizontal adjusting piece and a vertical adjusting piece. The horizontal adjusting piece comprises an optical
fiber fixing section and a horizontal adjusting section and is provided with a first through hole. The vertical adjusting part comprises a containing section, a vertical adjusting section and a positioning section, threads are arranged on the outer side of the vertical adjusting section, and the positioning section is cylindrical. The vertical adjusting part is provided with a second through hole and a third through hole, the center lines of the second through hole and the third through hole coincide, the
diameter of the second through hole is larger than that of the third through hole, and therefore a step structure is formed at the junction of the containing section and the vertical adjusting section, and the horizontal adjusting part is placed on the step structure. A plurality of horizontal adjusting holes are formed in the side wall of the containing section, and horizontal adjusters are arranged in the horizontal adjusting holes correspondingly and used for pushing the horizontal adjusting pieces in different directions. According to the technical scheme, the position of the optical
fiber head can be adjusted in the horizontal plane and the vertical direction, and therefore it is effectively ensured that the transmission path of optical signals is accurate.
