PURPOSE:To effect highly efficient excitation by adjusting the positions of the exciting end faces of a light source and an optical fiber such that the intensity of the light waves, which are reflected on the other end face other than the exciting end face of the optical fiber, may become the maximum. CONSTITUTION:The light waves 6 emanating from a light source 4 pass through an optical brancher 11 so that they are excited by the exciting end face 2 of an optical fiber 1. The light waves 7 thus excited are reflected on the other end face 3 so that the reflected light 10 advances toward the exciting end face 2 until it emanated therefrom. The reflected waves 10 are introduced into an optical detector 5 by an optical brancher 11. The position of the exciting end face 2 is adjusted by a fine adjusting jig 9 in a manner to maximize the output of the detector 5 so as to attain a highly effecient excitation. According to the present invention, the position adjusting operation of the exciting end face 2 and the operation for measuring the output of the detector 5 are accomplished adjacent to each other without fail. Thus, it is convenient and possible to eliminate wireless or wired communication for the above information transmission. |
