为了研究空间辐射导致的卫星光通信系统性能劣化，本文开展了光电核心器件的γ辐射实验。在辐照总剂量低于150krad的条件下，DFB激光器和LiNbO3光电调制器没有出现明显的性能变化，而EDFA器件表现出明显的增益衰减。实验结果表明，在卫星光通信系统的实际应用中应该更多的考虑高能粒子辐射所带来的影响。

To verify the potential space radiation-induced degradation of optical satellite communication system, theγray radiation experiments of its key photoelectric devices of transmitter set-ups have been developed. No obvi-ous performance degradations of the DFB laser and LiNbO3 modulator were found at the total dose less than 150krad. The EDFA seems to be the most radiation sensitive, and it comes to its malfunction through the radiation of 16.2krad. It is believed that the high energy particles’radiation effect should be first considered when it refers to the optical terminals’applications in the space.
