| 摘要 |
A distributed optical amplifier comprises an optical amplifying medium for distributed optical amplification, light supplying means for supplying a pump light to said optical amplifying medium, a pump light detecting part for detecting optical power of said pump light, adjusting means for adjusting an incident power of the light amplified with said optical amplifying medium, and control means for adjusting incident optical power of said light according to an output of said pump light detecting means. Because of this, the present invention can be controlled with a simplified structure of an optical power of an pump light, and an optical power of light to be amplified. A distributed optical amplifier as such can, for example, be applied in optical transmission systems.
