Soliton Technology In Agricultural Research Fidelity Transmission Of Information Over Long Distances

Soliton means under certain conditions, the use of ultra high-speed communication system a special envelope pulse nonlinear effects and group velocity dispersion fiber arising from interaction between the two, so that the light pulse stretching between wide interfere with each other, balanced transmission; with transmission distance as the growth of its pulse waveform amplitude remains relatively stable and unchanging characteristics. Meanwhile, the combination of optical soliton communication over very long distances, high-fidelity, high capacity and many other advantages in the field of information on agricultural things, will promote new all-optical communication technology applications in the field of agriculture information. In this paper, by fractional Fourier transform equation is solved numerically NLSE and higher-order correction term NLSE equation; discussed the loss coefficient initial chirp, the study of higher order nonlinear coefficient, the group velocity dispersion and other optical soliton communication system signal transmission effect analysis, and design some series of programs to suppress interference optical soliton communication process in order to achieve a balance soliton transmission, to further reduce the error rate. Among them, this innovation in the original amplitude ratio ranging method based on nonlinear gain control and set the filter device can effectively suppress the existence of superposition signal interference optical soliton communication. And through simulation results show:With the pulse wave propagation time and distance increments, high-speed digital optical communication systems between the soliton transmission characteristics are significantly improved, and soliton incident position consistent with the exit position, in this PSII soliton pulses over the waveform distortion also an effective remedy, greatly reducing signal attenuation, which will increase agricultural Things information transmission signal quality in a communication system, to achieve ultra-long-distance transmission has a certain practical significance.
