A new design for large-effective-area non-zero dispersion-shifted fiber (NZ
-DSF) for dense wavelength division multiplexing (DWDM) is presented. The G
aussian approximation method is used for calculating electrical field distr
ibution for the designed refractive index profile. The designed fiber has a
dispersion about 4 ps/nm/km and dispersion slope about 0.06 ps/nm(2)/km at
1.55 mu m operating wavelength, which can be used to avoid four-wave mixin
g (FWM). In addition, our calculation also shown that the designed fiber no
t only has a large effective area over 100 mu m(2) but also has low bending
loss (< 1.3 x 10(-3) dB with 30 mm bending radius and 100 turns) and low s
plice loss (< 6.38 x 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. (C) 20
