摘要
The electrical equalizing processing method for optical signal includes the following steps. An input optical signal is split into N channels of optical signals, in which N is an integer greater or equal to 2; band-pass filtering is performed on the split N channels of optical signals, in which central frequencies of a frequency band used in the performing of band-pass filtering on the N channels of optical signals are not exactly the same, and a passband of the frequency band and a frequency spectrum range of the N channels of optical signals overlap; the N channels of optical signals on which band-pass filtering is performed are converted into corresponding N channels of an analog electrical signal; an electrical equalizing process is performed on the N channels of the analog electrical signal to output an optical signal electrical equalizing processing result.
