Intersatellite laser communication can be considered as the consequent development of satellite communication technology, and the narrow laser beam and long communication distance cause the difficulty of establishing and keeping the link in complex space environment. 卫星间激光通信是未来卫星通信技术的重要发展方向,它在较为复杂的空间环境中进行,信号光束窄,传输距离长,给链路的建立和保持造成极大的困难。
In long distance transmission, optical signal need dynamic power equalization due to the unlinearity of serial link EDFA. 在长距离传输过程中,由于多个EDFA级联产生的非线性,提出了对增益进行动态均衡的要求。
