摘　　要：在光纤通信系统中,由于光纤的吸收和色散,光信号随着传输距离的增加而衰减,并产生波形畸变,使误码率增高,信息传输质量降低,限制了通信距离。为满足长距离通信需求,必须对光信号进行中继放大处理。光纤放大器具有输出功率大,增益高,工作频带宽,放大特性与偏振态、数据格式及系统比特率无关等特点。In optical fiber communication systems, due to the absorption and dispersion optical fiber, optical signal tenuation due to the distance increasing, and the waveform distortion, so that the error rate increased, quality of information transmission is reduced, limiting communication distance. In order to meet the demand of long distance communication, optical signal relay amplifying and processing must be used. Optical fiber amplifier has characteristics such as high output power, high gain, wide frequency band, amplification and polarization, data format and bit rate independent.
