Abstract
Soliton-type interaction is eliminated in optical fibre communications system by making the fibre appear to be a passive optical pipe to a signal to be transmitted along it. In particular, the signal to be transmitted is intensity modulated and at a first wavelength which is greater than the minimum dispersion wavelength of the fibre by a predetermined amount. This signal is launched simultaneously into the fibre with a signal of dark pulses of the same format but at a wavelength less than the minimum dispersion wavelength by the predetermined amount. As a result the light transmitted in the fibre is of constant intensity and soliton-type effects, which rely on intensity variation for their formation, do not occur.
