In the current context of high-altitude platform communication system, inter-satellite communication is remarkable and highly effective. The present work aims to develop an integrated data transmission system incorporating alternate mark inversion, wavelength-division multiplexing, and polarization interleaving scheme for transmitting data of eight channels, each carrying 20Gbps data over inter-satellite link of 5,000km. The performance of the integrated data transmission of 160Gbps data up to 5,000km will be evaluated by means of signal-to-noise ratio, total received power, and eye diagram.
