System analysis for optical inter-satellite link with varied parameter and pre-amplification

Inter-satellite optical wireless communication (Is-OWC) provides high date rate long distance outdoor links free of licensing issue. There is a line of sight communication which is affected by the alignment of satellite in space. In this paper, the system is designed with pre-amplification in the inter-satellite link to combat the losses with the amplification factor of 30 dBm and noise figure of 6dB. The system bit error rate (BER) and Q-factor is tracked for the performance evaluation by varying the parameters such as power, bit rate, distance etc. Inter-satellite OWC where BER targets as low as 10 −9 and Q-factor greater than 7 are typically aimed to achieve.
