A new design for large-effective-area non-zero dispersion-shifted fiber (NZ-DSF) for dense wavelength division multiplexing (DWDM) is presented. The Gaussian approximation method is used for calculating electrical field distribution for the designed refractive index profile. The designed fiber has a dispersion about 4 ps/nm/km and dispersion slope about 0.06 ps/nm2/km at 1.55 μm operating wavelength, which can be used to avoid four-wave mixing (FWM). In addition, our calculation also shown that the designed fiber not only has a large effective area over 100 μm2 but also has low bending loss (<1.3×10-3 dB with 30 mm bending radius and 100 turns) and low splice loss (<6.38×10-3 dB) with conventional fiber. The manufacturing tolerance of the fiber is found to be compatible with other types of known profile large-effective-area fibers. Thus, this newly designed fiber may be a good candidate for the long-haul DWDM fiber optic communications.
