<p>A system for adjusting an optical axis, wherein accuracy of an optical axis adjustment is improved. A mounting base (11), on which a plurality of electromagnets (11a) are arranged, mounts optics components. A magnetic force generation control section (13) supplies a specified current to a selected electromagnet (11a) to generate a magnetic force from the electromagnet (11a). A drive section (14) outputs an optical signal through the optics components. An optical receiver section (15) receives the optical signal to measure a received optical level. A control section (16) controls to select the electromagnet (11a) and to generate a magnetic force by supplying a current while monitoring the received optical level. The magnetic force generation control section (13) applies a magnetic force to a first optics component (21) via the mounting base (11) to suck the first optics component (21) to a second optics component (22). While a sucking state is kept between the first optics component (21) and the second optics component (22), the first optics component (21) is moved by a magnetic force such that an optimal value of the received optical level is achieved, thereby making an optical axis adjustment at an optical coupling section of the first optics component (21) and the second optics component (22).</p> |
