<p>An apparatus for adaptive dispersion compensation and the method thereof applied to adaptive dispersion compensation in an optical communication system comprises: input optical fiber, an optical tunable dispersion compensator, output optical fiber, a signaling system unit, a control logic unit which is used to calculate the adjustment value of the optical tunable dispersion compensator according to the dispersion performance information detected by the signaling system unit, then control the optical tunable dispersion compensator through feedback, thus adjust the dispersion compensation value of the optical dispersion compensator. The present invention overcomes the deficiency of the prior art by adaptively compensating the system dispersion in real time, thus the transmission quality of the system signal is effectively guaranteed, and in the case that the dispersion of the lines or optical network nodes varies, it can implement the adaptive dispersion compensating for multi-channel or single-channel system.</p> |
