A low-loss dispersion-modified single-mode fiber with low dispersion in the 1.5µm wavelength region has been designed and fabricated by using VAD method. A minimum loss of 0.23 dB/km at 1.55 µm and a small dispersion slope less than 0.023 ps/km/nm2 have been achieved around the zero-dispersion wavelength. Moreover, for the fist time, the tolerance of the core radius has been estimated by waveguide dispersion measurement.
