Abstract

With the increasing advent in digital age, it is required to set up an inter-satellite optical wireless communication (IsOWC) that can support ultra-high bit rate. Here the proposed IsOWC system is implemented using dense wavelength division multiplexing and sub carrier multiplexing. The proposed model is designed to work at three different wavelengths i.e. 850, 1064 and 1550 nm. The performance of the proposed models is measured in terms of Q-Factor and Bit error rate at a different transmitted optical power level and transmission bit rate. It is observed that by incorporating multiplexing techniques, higher transmission bit rates can be achieved. It is observed that maximum bit rate achieved by proposed IsOWC system employing multiplexing technique is multiple of the number of channels used in multiplexing i.e. four times the individual PSK modulated optical system. Finally, it is concluded that IsOWC system employing multiplexing techniques provides enhanced performance than single PSK modulated optical wave with existing optical infrastructure.
