N2 - We demonstrate and compare the generation and distribution of pulse position modulation (PPM) ultrawideband (UWB) signals, based on two different techniques using a gain-switched laser (GSL). One uses a GSL followed by two external modulators, while the second technique employs two laser diodes gain switched (GS) using a combined signal from a pattern generator and an RF signal generator. Bit-error-rate (BER) measurements and eye diagrams for UWB signals have been measured experimentally by using the different GS transmitter configurations and various fiber transmission distances. The simulation of both systems also has been carried out to verify our obtained results, which show the suitability of employing gain switching in a UWB over fiber (UWBoF) system to develop a reliable, simple, and low-cost technique for distributing the impulse-radio UWB (IR-UWB) pulses to the receiver destination.
