Sensitivity of Interferometric OSNR Measurements Techniques to the Variation in Signal Extinction Ratio
Sensitivity Interferometric OSNR Measurements Techniques Variation Signal Extinction Ratio
2015/7/31
We discuss calibration requirements for interferometric OSNR measurements. We show that variation of 0.25dB in the signal extinction ratio could result in large errors in OSNR for 42.8Gb/s modulated s...
