Paper Abstract

Commercial and military interest in free-space optical communication (FSO) is growing due to the high bandwidths, portability and high security. FSO systems with proper radio-frequency backup can provide a viable solution for the last mile problem The communication reliability of FSO has been being pay attention to. In this paper, an innovation solution of light power equalization is put forward and some technologies such that enlarging the dynamic range of light power gain and realizing communication for FSO in the condition of all-weather are studied, a method to implement the power equalization is also given in term of system-embedded, some experiments are implemented with a system self-fabricated, too, the experimental results shown that a wide range power equalization system on FSO can effectively reduce the influences from the random variation of atmospheric medium and other factors on the communication link path.
