Performance analysis and optimization of radio over fiber link

This paper is an attempt for a thorough appraisal of Radio over Fiber (RoF) systems. RoF system is divided into three main subsystems: Central Station (CS), Optical Fiber Network (OFN) and Base Station (BS). Each subsystem has its own functions, such as signal generation and modulation techniques at the central station, optical fiber characteristics and the detection at the base station. In this paper the merits of RoF systems have acknowledged. The radio frequency and optical modulation techniques, fiber characteristics and detection techniques are studied. The impact of technology choice is reviewed and comparison of optical modulation techniques, optical fiber and receiver are presented. There has been a significant efforts dedicated to the merging of radio frequency and optical fiber technologies targeting the distribution of radio wave signals, in the recent years. The domain of Radio over Fiber (RoF) technologies and systems took birth from these endeavors. This kind of systems promises a secure, cost-effective, and high-capacity mobile and wireless access for the prospect facilitation of broadband, interactive, and multimedia wireless services.
