Investigation of different configurations of amplifiers for inter satellite optical wireless transmission

In this article, different amplifiers such as erbium doped fiber amplifier, Raman amplifier and semiconductor optical amplifier, have been investigated in inter-satellite links on optical wireless communication system. It has been observed that EDFA performs better at long range than Raman and SOA amplification while later mentioned amplifiers perform well in the context of less distances. Q-Factor has been used for the assessment of the techniques to give the simulation results. The results show that EDFA which has simple design performs best at a higher transmission range for the data rate of 45 Gbps. EDFA systems has been simulated at different power levels and Q-factor has been observed at these power levels. The increasing aperture diameters of both transmitters and receivers have shown significant improvement in the performance system.
