We propose and experimentally demonstrate a chaotic ultra wideband (UWB) over fiber link based on optical feedback laser diode, in which UWB signals are generated and transmitted at three different bit rates of 360, 720 Mbit/s, and 1.44 Gbit/s respectively. Without utilizing any dispersion compensation module, the signal at a bit rate of 1.44 Gbit/s is detected using a digital signal processing receiver after 10 km fiber and 0.6 m wireless channel transmission. The power spectrum does not have any discrete spectral line because of the random output of the chaotic pulses, which means that the harmful effects of discrete spectral lines could be avoided with this method.
