The present invention provides a determination method and device for an optical signal-noise ratio (OSNR). The method comprises: determining a noise power correction factor k, and correcting, according to the determined k, noise power PN of a detected optical signal; and determining, according to the corrected noise power PASE, an optical signal-noise ratio (OSNR). The present invention solves the problem of great error of a detected optical signal-noise ratio in the related art, and further realizes an effect of reducing the error of the detected optical signal-noise ratio. |
