Abstract :
A new depressed-clad triangular-index-profile single-mode fibre with dispersion minimum shifted to the 1.55 ¿m region is investigated. Fibres with high cutoff wavelength (¿1.1 ¿m) and low dispersion slope (¿0.052 ps/km nm2) at their minimum dispersion wavelength (¿1.55 ¿m) were fabricated. Results from 226.7 km of fibre show an average loss of 0.241 dB/km at 1.55 ¿m and 0.232 dB/km at the loss minimum.
