Modern optical communication has advanced from the use of merely lengthy optical fibers to using features of the powerful wireless system and optics resulting in the use of lasers to transmit data at a much greater rate. This gave way to the optical wireless communication system growing roots into space communications. In this work, an intersatellite optical wireless communication link has been analyzed for studying the performance of the system considering linearly polarized modes. The link performance has been investigated in terms of the quality factor (Q factor) as a function of the transmission wavelength, detector type, data rate, distance, transmitter aperture diameter, and pointing error angle. The optimized results of the system reveal that the LP01 mode performs better with the non-return-to-zero modulation scheme at the 850 nm wavelength using a PIN photodiode.
