光孤子通信是实现超长距离高速通信的重要手段，它被认为是第五代光纤通信系统。近年来美、日、英等国相继进行了光孤子通信实验。美国的贝尔实验室先后进行了传输距离为4000km、6000km、15000km的光孤子传输实验，验证了光孤子跨洋通信的可能性，并且完成了32Gb/s传输90km无误 Optical soliton communication is an important means to realize ultra-long distance high-speed communication. It is considered as the fifth generation optical fiber communication system. In recent years, the United States, Japan, Britain and other countries have conducted optical soliton communication experiments. The Bell Labs in the United States conducted optical soliton transmission experiments with transmission distances of 4000km, 6000km and 15000km successively to verify the possibility of optical soliton transoceanic communications and completed a 90km transmission of 32Gb / s
