Analysis of fso system under clear and rain conditions

Abstract

Free Space Optical Communication System (FSOC) is one of the trending communication technologies where the communication will be based on the propagation of light. Light cannot travel everywhere alike due to the differences in atmospheric and climatic conditions. So, to bring this kind of system in practice, there is a requirement of testing it for various climatic and atmospheric conditions. Here in this work, such a testing was done on a system with Wide Division Multiplexing under very clear, clear and rainy conditions. The mathematical part for getting the attenuation levels is mentioned below in chapters. After examining the system, the variation of the bit rate and the quality factor, bit error rate were observed. Along with that, all the devices that will be using in the system are analyzed individually and got to know how each and every device work and how their variation would affect the entire communication system.
