<P>PROBLEM TO BE SOLVED: To provide an optical transmitter capable of preventing extreme deterioration in a waveform of an optical signal received at a transmission destination even when a transmission distance is subjected to change and to provide an optical communication system that is configured to include such the optical transmitter as above. <P>SOLUTION: The optical transmitter 21 which is used at a transmission source 13 of the optical communication system 11, outputs an optical signal in response to a received electric signal and transmits the optical signal to the transmission destination 15 of the optical communication system 11, and includes: a light emitting element 23 for outputting the optical signal to be transmitted to the transmission destination 15; a bias current source 25 and a modulation circuit 27 for driving the light emitting element 23 in response to the received electric signal; and a CPU 37 for controlling the bias current source 25 and the modulation circuit 27 so that the waveform of the optical signal received by the transmission destination 15 has prescribed quality by changing a difference between a minimum power and a maximum power of the power of the optical signal outputted from the light emitting element 23 on the basis of a dispersion between the transmission source 13 and the transmission destination 15. <P>COPYRIGHT: (C)2003,JPO |
