PDF-Noise Reduction High Frequency Modulation interferometric noise modula

following analysis since much smaller than the the in 9 is recognized as that due to the interferometrically converted laser phase noise the absence data modulation electric field at the fiber out. Those light waves may be sent through a transparent medium as a laser beam or con tained within a fiber optic cable The conversion from high frequencyhigh speed electrical signals into light can occur in two general waysapplied directly to the power Husheng Li.
