带内光噪声谱密度的测量
Measurement of In-Band Optical Noise Spectral Density
摘要：
我们提出了一种方法来测量带内光传输损伤的谱密度，而无需在接收器处进行相干电接收和数字信号处理。我们通过数值模拟确定了该方法的精度，并通过实验证明了其可行性，包括带内非线性失真功率密度的测量。
英文摘要：
We present a method to measure the spectral density of in-band optical transmission impairments without coherent electrical reception and digital signal processing at the receiver. We determine the method's accuracy by numerical simulations and show experimentally its feasibility, including the measure of in-band nonlinear distortions power densities.
