A signal light is coupled by a light coupler/splitter (31) with a 0.98 micron first pumping light (.lambda.1) generated by a first pumping light source (21), and the coupled light is launched into an Er-doped optical fiber (1). The signal light is optically amplified in the Er-doped optical fiber. A 1.48 micron second pumping light (.lambda.2) generated by second pumping light source (22) is launched into the Er-doped optical fiber (1) with a light coupler/splitter (32). This 1.48 micron pumping light contributes boost the amplified signal.
