Abstract
The effects of dispersion of light on a link having an optical transmission fibre characterised by positive dispersion and large positive relative dispersion slope can be reduced by employing a sufficient length of dispersion compensating fibre (“DCF”) so that dispersion slope on the link is substantially nulled and the net dispersion of the link is made negative. Optical signals launched on the link with a positive chirp will be compensated for by the net negative dispersion.
