Abstract

A nonzero dispersion shifted fiber design based on hole-assisted lightguide fiber is presented. The proposed fiber has low dispersion slope around $-0.01\mathrm{ps}/{\mathrm{nm}}^2\text{-}\mathrm{km}$ and small negative dispersion values over the wavelength range from 1530 to $1620\mathrm{nm}$. It can be used as a transmission medium for a long-haul dense wavelength-division-multiplexed system.
