Abstract

PURPOSE:To execute the two-way communication without limiting the action range of a worker by converting a voice to a prescribed form signal, transmitting it with an optical fiber and converting the light to an electric signal at an opponent side again. CONSTITUTION:When the voice of a first transmitter receiver 3a is inputted from the mike of one side head set, an electric wave is received to a second transmitter and receiver 3b based on the voice input. Then, the received signal is A/D-converted by a converting part 4 and light is outputted from a light input/output part 5 to a communication device 2 of an opponent. At the communication device 2, an input light is received by a light input/output part 5, converted to an electric signal, further, D/A converted by a converting part 4 and outputted to a second transmitter and receiver 3b. By the transmitter and receiver 3b, the supplied signal is converted to the electric wave and outputted to the transmitter and receiver 3a. Then, in the transmitter and receiver 3a, when the electric wave from the transmitter and receiver 3b is received, the voice is outputted from the headphone of other head set.
