<P>PROBLEM TO BE SOLVED: To provide a technique for appropriately adjusting the light intensity, when there are crosstalks in a device having a light intensity adjustment function. <P>SOLUTION: This optical transmission device 100 includes: a demultiplexing part 10a for demultiplexing an input wavelength multiplexing optical signal on wavelength basis; detection parts 15 (1-n) for detecting the light intensity of respective optical signals demultiplexed by the demultiplexing part 10a; adjustment parts 12 (1-n) for adjusting the output intensity of the respective optical signals, based on the light intensity detected by the detection parts 15 (1-n); a multiplexing part 11 for multiplexing the respective optical signals having output intensity adjusted by the adjustment parts 12 (1-n) that are to be output; and a correction device 16 for correcting detection values for the light intensity detected by the detection parts 15 (1-n). The correction device 16 calculates a value equivalent to the noise component added to each optical signal and removes the noise component from the light intensity detected by the detection part. <P>COPYRIGHT: (C)2010,JPO&INPIT |
