DISPERSION COMPENSATION MODULE

摘要

A dispersion compensation module, which has a function of compensating the wavelength dispersion produced in an optical transmission line and a construction with which the wavelength dependency of its transmission loss is mall and the module is easy to be inserted into an optical transmission system, comprising an input terminal and an output terminal of a signal light, a dispersion compensating means such as a dispersion compensation optical fiber and a loss equalizing means which compensates for a loss variation depending at least upon wavelengths in the dispersion compensating means.
