摘要：
DPSK based inter-satellite optical communication systems are exposed to space radiation environment. As the component of radiation environment, gamma irradiation will result in serious system performance degradation. In order to analyze the performance degradation, main devices employed in a DPSK based inter-satellite optical communication system were irradiated to a total dose of 10krad with the dose rate of 5rad/s using a Co-60 radiation source. Gamma irradiation impacts on devices were analyzed and on the basis, system performance degradation was simulated. BER was analyzed as a function of gamma radiation dose at laser transmitter and receiver. In addition, according to simulation results, we deemed that it is necessary to improve the radiation hardness of EDFA and laser transmitter so as to enhance system performance against gamma radiation.
