Design and Evaluation of 20Gbps Inter Satellite Optical Wireless Communication System for improved distance and performance

Abstract

In this present day world, satellite innovation plays a significant role. It is necessary to be sent data which obtained from the different orbits of satellites. So, it is required to have a link between the satellites to send these data. Hence, Inter satellite Optical Wireless Communication (Is-OWC) approach arises. Is-OWC system is high, small size, bandwidth, and light weight, low power and low cost and is therefore chosen over existing microwave satellite systems for reaching in space in the future. However the system has various limitations such as attenuations due to climate conditions, glimmers which limit its performance and diminishes its accessibility.The system also has trade-offs in the efficient design for higher distance coverage with better performance. In this paper, a 20 Gbs Is-OWC system with improved performance and longer distance is introduced. The proposed system is designed and evaluated using Optisystem Software 16 version. The proposed system provides better performance of Q factor and BER for the distance of 20,000 km. The distance is improved by using optical amplifier in the transmitter.
