  text: This paper presents optical duobinary and dicode signalling, as alternatives
    to the binary format, in order to improve the transmission performance in the
    presense of non-linear effects in a dense wavelength division multiplex (WDM)
    optical system. Duobinary signalling is applied to an optical system to explore
    the reduction of stimulated Brillouin scattering (SBS) effects. Duobinary signalling
    suppresses the SBS effects, and an eye-opening improvement of 0.25 to 1.2 dB is
    achieved relative to binary transmission over a range of input power levels. An
    experimental study demonstrates that duobinary modulation suppresses the four
    wave mixing (FWM) products of a dense WDM system by a maximum of 3 dB. The suppression
    is maintained over a range of channel spacings. An investigation of the impact
    of fibre dispersion on FWM products under binary, duobinary and dicode modulation
    in a dense WDM system is then performed, with interchannel spacing and optical
    power variation. This leads to the development of a set of guidelines for the
    application areas, in which it is appropriate to use duobinary or dicode modulation
    in WDM systems as a means of mitigating the impact of FWM.
