Disclosed are a decision feedback equalization apparatus and method, and an optical transmission system. The decision feedback equalization apparatus comprises a first equalizer, a first adder, a first decision unit, a second equalizer, a third equalizer, a second adder and a second decision unit. In the embodiments of the present invention, by means of multiplexing and cascading, the equalization performance of a decision feedback equalization apparatus is effectively improved, the problem that a receiver cannot receive the correct signal due to chromatic dispersion is solved, the bit error rate is further reduced, system stability is improved, and the requirements of a 40G to 100G system can be satisfied. |
