In this research article, the design and simulation analysis of 45×20Gbps Dense Wavelength Division Multiplexing (DWDM) Inter-satellite Optical Wireless Communication (IsOWC) System by taking into account the concept of reduced channel spacing of 50GHz has been done. The low power system is proposed and its performance analysis is observed for various parameters like transmission range and input laser line width. Moreover, the role of EDFA is noteworthy which does the task of amplification efficiently and made the system to work over a transmission range of 12500 km with acceptable Q-Factor and BER. Evaluation also has been proposed for different line codings in terms of Q-factor and BER.
