Design And Implimentation Of Rf Optical Link

Abstract

The separation between the RF antenna and the rest of the equipments of radar is considered as an important process. It is possible to achieve this task by converting the radar signals into corresponding optical signals, and sending it through an optical fiber in order to protect the personnel and instruments in critical positions. In this work, an RF optical communications system was designed to achieve this objective. The modulated RF signal was coupled via a matching circuit into optical fiber system. The output signal was detected. The power budget, maximum distance and maximum bit rate for the optical communication system was calculated. The efficiency of the optical RF and optical communication system was proved using the experimental results. Definite agreement between modulated RF signal and the output signal at the end of the fiber was achieved.
