ABSTRACT:
Disclosed is a gain-providing optical power equalizer which can equalize optical channel output or gain while amplifying signal output. In prior art technologies, optical power equalization has been achieved by attenuating signal output differently depending upon optical channels. However, the optical power equalizer of the present invention is characterized in that it achieves equalization of optical power by giving optical gain differently depending upon optical channels. According to the present invention, the output of optical channels can be adjusted to be flat or as desired without deteriorating signal to noise ratio.
