Title: Towards F6G:Trends and Challenges of Intergenerational Evolution of Optical Fiber Communication

After 20 years of rapid development, high-speed optical fiber communication systems are evolving to the sixth generation: Fiber access is moving from connected homes to connecting everything. The low-latency and high-quality requirements of new fiber access drive multiple access technologies from traditional Time division multiple access (TDMA) to new xDMA. Data center fiber interconnection has shifted from Intensity detection to coherent detection. Low power consumption and low cost are the key driving factors. Long-haul fiber transmission evolves from 400G to 800G and 1.6T, and the single-mode optical transmission capacity approaches 100T.
In the talk,we will discusses the development trend and challenges of the next-generation F6G high-speed optical fiber communication technology in terms of fiber access, data center optical interconnection, and long-haul optical transmission.
