Recently, during the Optical Fiber Communication Exhibition and Symposium (OFC) in the United States, ZTE Corporation achieved the first successful transmission of 34GBd single-carrier PM-256QAM signals over standard single-mode fiber (SSMF) for 80 kilometers in an experiment, and verified for the first time that probabilistic shaping technology can greatly improve the transmission performance of 400G 256QAM, creating a new 400G single-carrier transmission This has created a new 400G single-carrier transmission record, and laid the foundation for the research of single-carrier higher-rate optical transmission technology.

The experimental results have been included in the OFC as a highly scored paper, marking that ZTE Corporation's research results in the field of ultra 100G transmission are at the forefront of the world and widely recognized by the industry! It is reported that OFC highly scored paper papers only account for about 2% of the published papers. These papers are selected and recommended by globally renowned experts from industry and academia, and are highly authoritative in the field of fiber optic communications.

Dr. Jianjun Yu, Director of the North American Lightwave Research Institute of ZTE Corporation, said, "400G and higher speeds are the development direction for signal transmission in the next-generation high-speed optical networks. However, the bandwidth limitations of optoelectronic devices severely restrict the transmission performance of optical signals, so there is an urgent need to develop new technologies to realize long-distance transmission of high-speed optical signals to meet market demand. ZTE has achieved many breakthrough research results in this area."

The global optical communications industry is about to enter the ultra 100G era, and mainstream manufacturers are actively accelerating the research and development of ultra 100G optical transmission technologies and promoting the global deployment of ultra 100G products. Since its establishment in 2010, ZTE's North American Lightwave Research Institute has been based on cutting-edge research and development of 100G/ultra-100G high-speed signal transmission technology. It has successively overcome several key technologies in 100G/ultra-100G products, and has become an "acceleration engine" for global high-speed optical communication transmission technology.

At present, ZTE Corporation has always been in the industry's leading position in the field of 100G/Ultra 100G innovative technologies. There are more than 300 100G network application cases, and the total length of fiber optic of 100G networks constructed has reached more than 300,000 kilometers, which are widely used by many high-end operators in Asia-Pacific, Europe, and Latin America. In the latest global optical network market share report released by OVUM, a famous international consulting company, ZTE Corporation ranked the top two in global optical network market share.
