Zhi Zhang et al. from the School of Communication and Information Engineering, University of Electronic Science and Technology of China designed a constellation Reshaping chaotic encryption (CSCEn) scheme with statistical distribution controllable, as shown in FIG 2.  Firstly, orthogonal amplitud...

[Introduction] The wavelength division multiplexing technology can make full use of the huge bandwidth resources brought by the low-loss area of single-mode fiber. According to the frequency (or wavelength) of the light wave of each channel, divide the low-loss window of the fiber into several ch...
