<P>PROBLEM TO BE SOLVED: To provide an optical transmitter module capable of saving power without restricting the number of channels. <P>SOLUTION: In an optical transmitter module 100 for outputting optical signals having a plurality of frequencies, a plurality of laser diodes Ch1 to Ch4 are connected to each other in serial. A first current adjustment circuit 150 is connected to an electric power source 10 connected to anode sides of a plurality of laser diodes (Ch1 to Ch4), and adjusts current from the electric power source 10. A second current adjustment circuit 195 is connected to a plurality of laser diodes Ch1 to Ch4 respectively in parallel, and adjusts current flowing each of a plurality of laser diodes Ch1 to Ch4 among current adjusted by the first current adjustment circuit 150. <P>COPYRIGHT: (C)2013,JPO&INPIT |
