摘要：A method for detecting an optical signal-to-noise ratio (OSNR). A wavelengthlabel loading end (11) loads a wavelength label signal in an optical signal, and sends a

loading modulation depth of the wavelength label signal to an OSNR detection end (12)through a wavelength label channel or an optical monitoring channel. The OSNRdetection end (12) obtains a loading modulation depth of a wavelength label signalloaded in each wavelength optical signal, parses the wavelength label signal to obtain acurrent modulation depth of the wavelength label signal, and obtains an OSNR value ofeach wavelength optical signal according to the loading modulation depth and thecurrent modulation depth of the wavelength label signal. A system and device fordetecting an OSNR applicable to OSNR tests of present optical signals with high rates of40G, 100G, etc., and in particular to OSNR tests of polarization multiplexing opticalsignals.
