| Abstract: | A cascaded EDFA system which is automatic gain controlled has been developed,and We demonstrate the feasibility of its application in the high speed long wavelength intersatellite optical communication through numerical analogue based on the theoretical model of Er 3+ doped fiber amplifier.The character of high speed light pulse distortion and the fluency of the amplified spontaneous emission on the SNR gain under high power signal and pumper are analyzed. |
