Intersatellite communication is the process of transmitting information between satellites. Optical communication in intersatellite system involves the process of transmitting information with light as carrier wave. While transmitting information due to some noises or any other external factors some losses may occur. In this study the reduction in nose by the use of preamplifier at the receiver end may be analyzed. Preamplifier is said to have the capability of detecting and correcting errors. Hence in the output graph we may obtain the increase in signal strength with the reduction in noise. Bit Error Rate calculation may also be done. Telescope used in the block may act as terminating equipment which may reduce the reduction in cost of the entire system.
