On June 13th, at the "China Optical Network Seminar and China FTTH Forum" held today, Wang Guangquan, director of the Network Technology Research Department of China Unicom Network Technology Research Institute, published the theme of "5G and Cloud Age Optical Network Development Ideas" In the speech, he said that 5G and the cloud era put forward three requirements for optical networks. First, 5G's huge bandwidth capacity requirements and new network architecture (cloud and DC deployment at different levels) bring opportunities and challenges to optical networks (backbone and metropolitan area). 5G has also become a backbone and metropolitan area network expansion and upgrade. The important driver. In the backbone network, the proportion of 5G traffic will increase significantly; in the metropolitan area network, the proportion of 5G mobile traffic will gradually converge with the fixed bandwidth traffic, and the current proportion is very small. Secondly, the data center interconnection of the cloud network brings great interconnect bandwidth requirements to the optical network. As the trend and proportion of network cloudization gradually increase, the interconnection needs of data centers will also expand rapidly, and the performance requirements of optical networks will increase. Finally, the 5G large-scale network construction has effectively promoted the pace of network reconfiguration using SDN/NFV, and requires an intelligent elastic optical network that spans professional integration and cross-city networking.
