Abstract:
1. An optical fiber characterized by: a dispersion of not less than 2 ps/nm/km and not more than 10 ps/nm/km at a wavelength of 1550 nm; an effective area of 65 μm a positive dispersion slope at a wavelength of 1550 nm; a zero dispersion wavelength outside the wavelength range of 1400 nm to 1460 nm; a dispersion of not less than −10 ps/nm/km and not more than −2 ps/nm/km at a wavelength of 1400 nm to 1460 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.
