Abstract :
Protected Multichannel FSO communication system is described. FSO communication channel speckle distribution is considered. An Influence of both small and large size photodetectors is analyzed. Possibility to realize a protected channel of communication is presented. Sample of optical systems optimization is given. An Eyesafe wavelength optical band receiving module design is presented. Sensitivity and noise parameters are considered. Variable schematic decisions with different types of photodiodes are submitted. Technical solutions to optimize design are presented. Parameters of designed Photodetector module are given.
