The increasing demand for high data rates in wireless networks indicates Radio-over-Fiber (RoF) systems as a good candidate for physical layer infrastructure in the development of future high-speed wireless communication systems. In this work, the performance of a distributed feedback (DFB) laser is evaluated in order to exploit its operational parameters and identify its limitations for the purpose of utilization in broadband RoF systems. It is shown that the laser’s intrinsic non-linearity restrictions can be tolerated by appropriate adjustment of the operating parameters and choice of proper modulation schemes.
