| description | The uprising of rare-earth-doped fiber amplifier technology provides an effective solution to signal power compensation for interstellar optical communication systems, but significant signal power attenuation induced by spatial irradiation has ever been a significant issue to be resolved in practical applications. In order to explore the impact of radiation on the performances of high-speed differential phase shift keying (DPSK) satellite communication systems using EDFA preamplification technique, the irradiation effect on output central wavelength, half width, and noise figure (<italic>NF</italic>) of EDFA has been studied. Different anti-irradiation schemes employing Co<sup>60</sup> radiation sources with a total radiation dose of up to 300 krad are compared from experimental perspective to optimize the anti-irradiation scheme. Radiation-induced attenuation (RIA) as well as increase in <italic>NF</italic> of the EDFA is considered in our simulation model, by which the limitations of the physical shielding scheme could be clarified and quantitatively evaluated<italic>.</italic> We conclude that compared to the RIA effect, the increase in noise figure plays a major role in the degradation of communication systems. In addition, according to simulation results of two high-speed DPSK systems, some anti-irradiation schemes are proposed as recommendations for future applications of EDFA-assisted optical systems under radiation exposure environments. |
