Abstract
Radio over Fiber refers to a technology whereby light is modulated by a radio signal and transmitted over an optical fiber link to facilitate wireless access. In RoF system, wireless signals are transported in optical form between a central station and a set of base stations before being radiated through the air. Each base station is adapted to communicate over a radio link with at least one user's mobile station located within the radio range of said base station. In this paper, Optical SSB signal is specifically selected as it has tolerance for power degradation due to dispersion effects over a length of fiber and phase noise from RF oscillator Linewidth and laser linewidth is evaluated by using parameter CNR (carrier to noise ratio). Signal degradation is studied for various lengths of fibers in the presence of fiber chromatic dispersion.
