Simulated investigation of ultra-wideband pulse signal generation by fiber-optic technology
Simulation technique is used to investigate the generation and distribution of Ultra-Wideband(UWB) pulse signals in fiber-optic transmissions.The numerical analysis of the system frequency response shows that it has the band-pass filter characteristics at lower frequency band and the shorter the central wavelength
the wider the lower frequency bandwidth.Transmission performance simulation for 12.5 Gbit/s pseudo-random sequence also shows that Gaussian pulse signals in time domain after fiber-optic transmission is close to FCC UWB pulse waveform template
while the signal spectrum in frequency domain to FCC spectrum specification.
