Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, and relates to a chaotic optical fiber communication method based on electrical domain compensation. Background technique [0002] With the advent of the information age, people's demand for super-large-scale multimedia information has grown rapidly, and the high-speed, efficient and safe transmission of information has become a fundamental issue in the field of communication. Optical fiber uses light waves as information carriers, and has outstanding advantages such as ultra-high bandwidth, ultra-large capacity, ultra-long distance, and strong anti-interference, and plays an irreplaceable role in wired high-speed information transmission. However, in the conventional optical fiber communication system, the transmitted data information is prone to leakage or illegal tampering, which is accompanied by serious security risks. [0003] Since the wide-spectrum characteristics of ...
