Electronic chromatic dispersion compensation equalizer for optical communication and tap regulation method

The invention discloses an electronic chromatic dispersion compensation equalizer for optical communication and a method for adjusting a tap thereof. The electronic chromatic dispersion compensation equalizer comprises two symmetrical linear equalizers arranged at a transmitting terminal and a receiving terminal respectively. The structure of the chromatic electronic dispersion compensation equalizer is simpler than a decision feedback equalizer, and the performance of the chromatic electronic dispersion compensation equalizer is better than the linear equalizer. The invention adopts linear fragmentation algorithm to arrange symmetric linear equalizers at the transmitting and the receiving terminals respectively so as to acquire better anti-interference effect than normal linear equalizers and reduce complexity of the system. The invention further uses adjustment step factors to adjust the tap coefficient of the equalizer, and the method is simple in algorithm and good in convergence effect.
