Summary:A laser relay module in a free space optical communication network includes: a beacon source for generating an optical beacon signal for aligning a communication channel of a source optical node to a communication channel of a receiving optical node; a beacon inserter for encoding the optical beacon signal with switching information; a telescope for transmitting the encoded optical beacon signal to the receiving optical node; a beacon detector for detecting received switching information from the modulated optical beacon signal, wherein the receiving optical node uses the encoded optical beacon signal to align communication channel of the receiving optical node with communication channel of the source optical node; and a processor for using the detected switching information to change configuration of an optical switch matrix to direct received data to a next optical node in the free space optical communication network.
