An optical fiber cable has a sectional area of Ac [μm2] and housing a number N of optical fibers. A transmission loss αdB [dB/km], a mode field diameter W [μm], an effective area Aeff [μm2], an effective length Leff [km], and a wavelength dispersion D [ps/nm/km] of each of the optical fibers at a wavelength of 1550 nm satisfy a predetermined equation.
