Abstract :
This paper presents the transmission of microwave & Quadrature Amplitude Modulated (QAM) signals in a Radio Over Fiber (ROF) system at a wavelength of 1550nm with a transmission rate of 16 Mb/s. The ROF system is characterised by having a fiber optic link and also a free-space radio path. The fiber wireless system network consist of a central station, a remote access unit and an optical fiber link. Here in this system external modulators technique that is an electroabsorption modulator (EAM) is used. The simulation is done using MATLAB
