Abstract :
A novel method of measuring the distributed zero dispersion wavelength (λ0) along the length of a fibre is proposed: it uses the dispersion dependent idler pulse generation induced by modulation instability. The λ0 distribution of a 10 km fibre is successfully measured without cutting the fibre into short pieces. The measured distribution is compared with the average values of each span as measured using the conventional cutback method
