PROBLEM TO BE SOLVED: To provide a dispersion compensation module for realizing dispersion compensation of a transmission path in a high-speed WDM transmission by inhibiting a variance in residual wavelength dispersion in a transmission path after dispersion compensation, and to provide a dispersion compensation module suitable for transmission in a plurality of wavelength bands. SOLUTION: The dispersion compensation module having at least two pieces of dispersion compensation fibers for compensating for dispersion and dispersion slope of signal wavelength bands accumulated in an optical fiber for transmission, provided with a dispersion compensation fiber 11 having a dispersion value D1 [ps/nm/km] and a dispersion slope S1 [ps/nm<SP>2</SP>/km], a dispersion compensation fiber 12 having a dispersion value D2 [ps/nm/km] different from the dispersion value D1 and a dispersion slope S2 [ps/nm<SP>2</SP>/km] different from the dispersion slope S1, and a connection part 13 for connecting the dispersion compensation fibers 11, 12 in series.
