Abstract
The analysis of the parameters of a high-speed information transmission system using dispersion-managed solitons is carried out. It is shown that the quality of information transmission can be increased by choosing the input–output point of the symbol sequence on the dispersion map. Fiber-optics soliton information systems are distinguished by high stability of data transmission. However, in real fibers, it is possible to realize the soliton regime at certain approximations. For high-speed WDM systems, it is advisable to use the dispersion-managed soliton. The feature of this mode is the low threshold level forming soliton in an optical fiber, which ensures a low level of inter-channel interference. The dispersion map parameters largely determine the bit rate. However, with the given parameters of the dispersion map, it is possible to select the parameters of the symbol pulse, providing a higher bit rate and higher signal-to-noise ratio in the system. A computer simulation of a fiber-optic data transmission system using optical solitons has been carried out. It is shown that when constructing a system with a dispersion map, which assumes input–output of spectrally limited pulses, the quality of data transmission increases. The method for the optimization of the parameters of the soliton data system is presented.KeywordsFiber optics transmission systemOptical soliton
