<P>PROBLEM TO BE SOLVED: To provide an optical transceiver etc. capable of easily adjusting optical power on a transmission side, thereby reducing power consumption and extending the life of an apparatus. <P>SOLUTION: In an optical transceiver 10, an optical transmission unit 10a comprises a laser diode element 12 for emitting a transmission optical signal and a laser diode driver 11 which converts a transmission data signal to an output current for driving the laser diode element to perform the light emission, and an optical reception unit 10b comprises a photodiode element 13 which receives a reception optical signal and generates a reception optical current and a transimpedance amplifier 14 for amplification, voltage conversion, and output of the reception optical current. The laser diode driver 11 inputs to the laser diode element the output current obtained by multiplying the reception optical current by a predetermined ratio. <P>COPYRIGHT: (C)2013,JPO&INPIT |
