Abstract:
An optical fiber having a chromatic dispersion of +1.0 ps/nm/km or more at 1460 nm wavelength band, a dispersion slope of 0.04 ps/nm2/km or less at 1550 nm wavelength band, and a cutoff wavelength of 1450 nm or less, wherein a relationship of an RDS, which is a value of the dispersion slope to the chromatic dispersion, to a wavelength &lgr; is âˆ’1.67Ã—10âˆ’5&lgr;+0.0300&gE;RDS(&lgr;)&gE;âˆ’1.67Ã—10âˆ’5&lgr;+0.0285.
