ABSTRACT:
A optical talk set has a talk set including bending means for bending an optical fiber of an optical cable, vibration applying means for applying vibration to the optical fiber, and a light-receiving element for receiving light leaking upon bending of the optical fiber and for converting the light into electricity, a signal transmitting/receiving line having an input/output terminal, 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 enclosing the converter, the signal transmitting/receiving line, and the light-receiving element. The input/output terminal of the signal transmitting/receiving line is provided so as to be exposed to the outside of the housing, by virtue of which a call can be made without opening the housing, facilitating maintenance, etc. of an optical fiber path.
