PROBLEM TO BE SOLVED: To provide the communication equipment making accurate communication independently of a receiver of an opposite party. SOLUTION: The equipment is provided with a high speed LED 5 and a low speed LED 6 whose wavelength differs from each other. A CPU 2 is provided with a high speed signal generating section 2a and a low speed signal generating section 2b generating an information signal in matching the stimulated wavelength of the high speed LED 5 and the low speed LED 6 and an information signal changeover section 2c selecting an output of each information signal in matching the stimulated wavelength of the high speed LED 5 and the low speed LED 6 to the high speed LED 5 or the low speed LED 6, a data confirmation input line 7 detecting a signal lighted from the low speed LED 6 and the CPU 2 stops the light emission from the low speed LED 6 based on a change in a communication waveform or an error rate of communication data detected by the data confirmation input line 7. |
