ABSTRACT:
The present invention provides a variable optical dispersion compensating module comprised of (a) an optical dispersion compensating unit having an input optical switch, an optical dispersion compensating fiber, connected to the optical switch, having a predetermined optical dispersion amount, a bypass path for bypassing the optical dispersion compensating fiber, and an output optical switch connected to the optical dispersion compensating fiber and the bypass path, (b) an optical dispersion compensating circuit with at least one of the unit connected in series, and (c) an optical attenuator provided, in the direction of an optical path, after the input optical switch or before the output optical switch of the optical dispersion compensating circuit.
