A dispersion-insensitive UWB over fiber system based on a photonic microwave bandpass filter

A novel technique to generate and distribute UWB signals over optical fiber that is insensitive to fiber dispersion is proposed and demonstrated. The entire system is equivalent to a photonic microwave bandpass filter with a constant frequency response for a different distribution distance. The proposed system is evaluated by a numerical simulation and verified by an experiment. The dispersion insensitivity makes it suitable for integration into a WDM-PON network.
