A optical talk set has a talk set (16) including bending means for bending an optical fiber (12, 13) of an optical cable (10, 11), vibration applying means for applying vibration to the optical fiber (12, 13), and a light-receiving element for receiving light leaking upon bending of the optical fiber (12, 13) and for converting the light into electricity, a signal transmitting/receiving line (17) having an input/output terminal (18), for enabling transmission of signals to be input to the bending means and the vibration applying means and a signal output from the light-receiving element, and a housing (19) enclosing the converter (16), the signal transmitting/receiving line (17), and the light-receiving element. The input/output terminal (18) of the signal transmitting/receiving line (17) is provided so as to be exposed to the outside of the housing (19), by virtue of which a call can be made without opening the housing, facilitating maintenance, etc. of an optical fiber path. <IMAGE> |
