摘要：An optical fiber characterized by a dispersion of not less than 2 ps/nm/km andnot more than 10 ps/nm/km at a wavelength of 1550 nm, an effective area of 65

&mgr;mor more at a wavelength of 1550 nm, a positive dispersion slope at a wavelength

of 1550 nm, a zero dispersion wavelength outside the wavelength range of 1400 nm to1460 nm, an absolute value of dispersion of not less than 2 ps/nm/km and not more than10 ps/nm/km at a wavelength of 1400 nm, a cutoff wavelength of 1400 nm or shorter,and a transmission loss of 0.40 dB/km or less at a wavelength of 1400 nm is provided. Byusing the optical fiber of the present invention, the WDM transmission both in the 1.55&mgr;m wavelength band and in the wavelength range between 1400 nm to 1460 nm isrealized.
