Abstract: PROBLEM TO BE SOLVED: To embody a no-loss module for compensating the color dispersion of a dispersive transmission fiber which operates at a system wavelength of about 1550 nm. SOLUTION: The module has (a) an input coupling means for inputting a signal, (b) a dispersion compensation fiber(DCF) 3 including a DCF unit consisting of a fiber which is negative in the code of dispersion and has the absolute value of dispersion of at least 50 ps/nm-km, (c) an amplifier means which offsets the loss by this DCF 3 and (d) a coupling means for connecting this amplifier means to the DCF 3. The amplifier means described above has at least one pump 5 which radiates pump energy at the wavelength shorter than the system wavelength, by which the signal in the DCF 3 is amplified by stimulated Raman scattering. The module further can have an adjustment DCF spool for fine adjustment of the dispersion. Either the positive or negative code of the dispersion of the adjustment DCF spool is possible and the absolute value of the dispersion is made twice that of the desired accuracy.
