Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, and in particular relates to an intelligent optical information processing technology for the coupling effect of magneto-optical effect and nonlinear effect of optical fiber. Background technique [0002] With the rapid development of optical fiber communication technology, the advent of fiber-to-the-home (FTTH) and triple play, high-speed, intelligent all-optical networks have become a crucial development direction in the field of optical communication, requiring optical information processing to be dynamic and intelligent. . However, optical signals are affected by many factors, such as group velocity dispersion, amplifier noise accumulation, and mutual crosstalk within or between channels. In order to overcome the degradation of optical signals caused by these factors and improve the transmission quality, it is necessary to use all-optical 3R regeneration (re-amplification...
