200 GHz-spacing WDM transmission system employing ultrawideband optical signals

In this paper, we experimentally demonstrate a wavelength division multiplexing (WDM) transmission system supporting converged transport of multi-wavelength ultrawideband (UWB) signals. Optical signals of 8×10 Gb/s are successfully transmitted through a 25 km single mode fiber (SMF). This paper mainly studies the influence and change of the waveforms and spectra of the optical signals during the co-propagation process.
