Dispersion-compensating module

摘要

The present invention relates to a dispersion-compensating module functioning to compensate for the chromatic deviation occurring in an optical transmission line and comprising a structure adapted to be easily inserted in an optical transmission system. The dispersion-compensating module according to the present invention comprises an input end and an output end for signal light, and also comprises dispersion-compensating means such as a dispersion-compensating optical fiber or the like, and loss-equalizing means for compensating for at least the wavelength-dependent loss deviation in the dispersion-compensating means.
