ABSTRACT:
An optical fiber capable of compensating in the L-band both the chromatic dispersion and dispersion slope of a positive-dispersion optical fiber, an optical transmission line incorporating the optical fiber, and an optical communications system incorporating the optical transmission line. An optical communications system1comprises an optical transmission line10, an optical transmitter20, and an optical receiver30. The optical transmission line10comprises an optical fiber11and an optical fiber12that are mutually fusion-spliced. The optical fiber12has at a wavelength of 1,590 nm a chromatic dispersion, D2, and a dispersion slope, S2, that satisfy the formulae −200 ps
m/km≦D2≦−50 ps
m/km, and 0.009
m≦S2/D2.
