Abstract:
Embodiments of this disclosure provide an apparatus and method for monitoring an optical signal to noise ratio, a receiver and a communication system. The apparatus for monitoring an optical signal to noise ratio includes extracting signals from signals obtained after an equalization processing is performed on optical signals received by a receiver, the optical signals including signals of known frequencies, and the signals extracted having the same spectral characteristics as the signals of known frequencies; correcting, according to filtering parameters used in the equalization processing, the signals extracted and outputting corrected signals; and calculating an optical signal to noise ratio according to the corrected signals. According to the embodiments of this disclosure, the optical signal to noise ratio may be calculated more accurately.
