Abstract :
We propose and experimentally demonstrate generation and distribution of optimally power efficient impulse-radio ultra-wideband (IR-UWB) waveforms over passive optical networks (PONs) for high bit rate wireless data distribution in the home. We use a reconfigurable UWB pulse generator in the context of radio over fiber delivery over a PON for fiber to the home/premises services. The single mode fiber PON feeder is used to create the required dispersion for the frequency-to-time conversion for optical pulse shaping. As the feeder length varies for different PONs, a tunable UWB pulse generator compensates for variable dispersion. We can compensate the effect of feeder length over a high dynamic range. We experimentally demonstrate the generation of the same UWB pulse for feeder lengths of 17, 27.5 and 35.5 km by tuning the optical pulse generator.
