Abstract:

Ultra-high-speed, ultra-large-capacity and ultra-long-haul(3U)optical transmission as a new mode of communication can greatly promote the next generation of optical internet and broadband mobile communication network development and technological progress, therefore 3U has become the focus of international high-tech intellectual property and competition ground. Starting from the background and significance of 3U research, the three scientific problems in 3U were given, and the architecture, basic theory and key technology of 3U optical transmission were introduced. Finally, the verification platform was introduced together with the important experiments completed on the platform, as well as the industrial application of the innovative achievements.

Key words: ultra-high-speed, ultra-large-capacity, ultra-long-haul, optical transmission, multi-wavelength source, high spectral efficiency, optical coding, optical modulation, optical parametric amplification, nonlinear suppression, dispersion management
