    • An apparatus for compensating for dispersion of an optical fiber in an optical line, which compensates for dispersion generated in the optical fiber when an optical signal produced by an optical transmitter is transmitted to an optical receiver via the optical line, is provided. The apparatus includes a dispersion compensation fiber for compensating an optical signal produced by an optical transmitter in order to predict and compensate for dispersion generated in the optical line, a dispersion compensation filter for controlling the dispersion value of the optical signal dispersion-compensated by the dispersion compensation fiber, to gain zero overall dispersion, and an optical amplifier for amplifying a signal having a dispersion value adjusted by the dispersion compensation filter and outputting the result to the optical line. Accordingly, it is easy to zero a dispersion value of an optical fiber in the optical line by regulation of the dispersion compensation fiber and filter. When the dispersion value varies with the deterioration of the optical fiber in the optical line, continuous compensation is not possible using only the dispersion compensation fiber. However, continuous compensation is easily made by adding the dispersion compensation filter.
