How to test the signal-to-noise ratio of an optical module
IEC 61280-2-9:2009 provides a parameter definition and a test method for obtaining optical signal-to-noise ratio (OSNR) using apparatus that measures the optical spectrum at a multichannel interface. OSNR stands for Optical Signal to Noise Ratio. It's a crucial parameter for estimating the performance of optical networks. Because noise measurement is made on an optical spectrum analyzer, the measured noise does not. The quality of optical and other measurements is often characterized by a signal-to-noise ratio (SNR, S/N ratio). Built on the award-winning VIAVI MAP-300 Optical Test platform, the MAP delivers a scalable test system that can be configured.
