This part of IEC 61280 provides a parameter definition and a test method for obtaining opticalsignal-to-noise ratio (OSNR) using apparatus that measures the optical spectrum at amultichannel interface. Because noise measurement is made on an optical spectrum analyzer,the measured noise does not include source relative intensity noise (RIN) or receiver noise.Three implementations for an optical spectrum analyser (OSA) are discussed: a diffractiongrating-based OSA, a Michelson interferometer-based OSA, and a Fabry-Perot-based OSA.Performance characteristics of the OSA that affect OSNR measurement accuracy areprovided.
