摘要：A dispersion flat optical fiber having a structure for effectively suppressi ng the development of a non-linear optical phenomenon and suitable for a wavelength multiplexing soliton transmission using an optical amplifier. It has various characteristics at a wavelength of 1,550 nm, including a dispersion having an absolute value of not greater than 5 ps/nm/km, an effective sectional area of at least 45 .mu.m2, a dispersion slope of not greater than 0.03 and a cut-off wavelength of at least 1.0 .mu.m at a length of 2 m.
