In 2019, China's 5G technology and network development will enter the trial commercial phase. As a national development strategy, 5G will combine the application and construction of new-generation information technologies such as the Internet of Things, Industrial Internet, cloud computing, big data, artificial intelligence, and blockchain. Digital China will carry out supply-side reforms of China's traditional industries and create a smart economic society, thereby driving a new round of economic growth in China. This development trend will profoundly affect and change the development pattern of the optical communication industry, and accelerate the development of the optical communication industry towards the intelligent optical communication industry. 5G and the Internet of Things, the new generation of information and communication technology put forward new requirements on optical transmission networks, optical access network technologies and standards, network construction and deployment, etc. At the same time, new optical components and modules are required to adapt to new technologies and Application needs. Based on the above background analysis, industry experts in the optical communications field will be invited to focus on "new technologies, new applications and new formats of optical networks", "integrated development of optical broadband access and smart industries", "optoelectronic devices and optoelectronic integration technologies" and "down One generation of data center optical interconnect technology "," 5G + industry + next-generation information technology "and other topics, held the" 5G Era Optical Communication Industry Transformation and Application Innovation Development Forum "in 2019.

The fifth-generation mobile communication (5G) technology is about to enter the commercialization process. Its new service characteristics and higher indicators require new challenges to the bearer network architecture and technical solutions at all layers. For 5G carrying, 25/50 / 100Gb / s new high-speed optical modules will be gradually introduced in the fronthaul, midhaul and backhaul access layers, and N × 100/200 / 400Gb / s high-speed optical modules will be introduced in the backhaul convergence and core layers. Introduced. 5G optical modules have different solutions in terms of transmission distance, modulation method, operating temperature, and packaging. They need to be selected according to application scenarios, costs, and other factors.
The introduction of new 5G service features, wireless access network structure, and core network architecture innovations provide opportunities for a new round of rapid development of bearer technology. The 5G bearer network presents three major performance requirements and six networking function requirements. Various factors, such as service characteristics, operator technology architecture, and future evolution ideas, have led the 5G bearer to develop in parallel with multiple technology solutions. "5G commercial, bearer first". As the scale of 5G live network trials and the pre-commercialization process accelerate, 5G bearer technology solutions will continue to strengthen convergence and innovation.
