Free Space Optical links have gained significant importance in future generation space optical communication, particularly to establish a reliable optical inter-satellite optical wireless link between two satellite platforms. But the performance of Optical wireless link is degraded very much due to vibration imposed by various sources like; thermal storms, other heavy particles collisions. To address this problem a fiber bundle-based receiver approach other than conventional array of photodetector is required to mitigate the effects of pointing error. The result shows that the effect of pointing errors is reduced in the fiber bundle-based receiver system in compare to conventional receiver and this newly designed receiver system is able to cope up to 10 urad pointing error to achieve minimum Bit Error Rate (BER) and Q-factor for a data rate of 1 Gbps over a 200 km distance. It is practically implementable in Low Earth Orbit (LEO) satellite optical wireless communication link
