Abstract

Abstract: With the continuous improvement of business bandwidth, network performance, network security and network management and control requirements in 5G and cloud era, optical network will further directly provide connection oriented network services. At the same time, it will also become a solid base for operator networks and a comprehensive service carrier to meet the needs of different bandwidth, performance, security and service levels in cloud era. The development of optical network is facing great opportunities and challenges. The architecture of alloptical infrastructure in the cloud era is described. Based on this architecture, the key technologies of optical network such as ultra-high speed transmission, all-optical integrated access, SDN management and control, opening and decoupling, intelligent enhancement and optical network digital twinning are analyzed.

Key words: all-optical network, all-optical infrastructure, SDN, digital twin optical network
