A dispersion compensator of the present invention includes a dispersion compensation fiber and a polarization conversion mirror. The dispersion compensation fiber has color dispersion of a sign opposite to the sign of the color dispersion of the optical fiber transmission line, and the length thereof is set so as to conform to the value of the color dispersion of the optical fiber transmission line. Light propagating in the optical fiber transmission line then propagates in the dispersion compensation fiber from a first end toward a second end of it and is supplied to the polarization conversion mirror. The light supplied to the polarization conversion mirror is converted into light of a polarization condition orthogonal and time-reversed to the polarization condition of the light supplied to the polarization conversion mirror, and propagates in the dispersion compensation fiber from the second end toward the first end of it. This enables compensation not only for color dispersion but also for polarization mode dispersion.
