Summary: 
Low-loss dispersion-free single-mode fibers near 1.5 µm were fabricated by controlling their waveguide dispersion. The deviation of the zero-dispersion wavelength from the calculated one was within 0.02 µm, and the minimum loss of the fiber was 0.46 dB/km at 1.56 µm. The pulse broadening in the 20 km long fiber was measured to be 1.3 ps/km/nm at 1.50 µm. These results confirmed that it is beneficial to use the dispersion-free single-mode fibers for high capacity and long distance transmission media.
