Interferometric optical signal-to-noise ratio measurement using a calibration factor |
摘要 |
Systems and methods are described that measure the OSNR of an optical channel. Embodiments provide OSNR measurement methods that distinguish the intensities of the coherent modulated signal from the incoherent noise intensity occupying the same optical band using a calibration factor ζ. |
