With a particular single-span experimental setup isolating the contribution from nonlinear phase noise, the measured signal-to-noise ratio (SNR) penalty is within 0.15 dB of the theoretical results in a range of SNR penalty less than 1.5 dB. For a SNR penalty less than 1 dB, both theory and experiment indicate that the mean nonlinear phase shift should be less than 0.33 rad.application/pdf107891 bytesapplication/pdfzh-TW國立臺灣大學電信工程學研究所差分相位鍵移非線性相位雜訊Kerr 效應光纖非線性效應DPSKNonlinear phase noiseKerr effectFiber nonlinearities高速DPSK 訊號在光纖通信系統的傳輸(2/2)High-Speed Transmission of DPSK Signals in Lightwave Systemsreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/20317/1/932213E002061.pdf
