To meet the next-generation system bandwidth requirement, recently industry and standard bodies are aiming at 800GE and 1.6TE. The next generation switch is targeting 100T capacity as well. The next speed node of 200+ Gbps per lane becomes critical to scale the switch capacity and efficiency of networking bandwidth. In this talk Cathy will discuss and share the insights on what is needed for the next speed note 224 Gbps, focusing on design challenges and solutions for next generation high-speed networking technologies. She will provide the audience an opportunity to hear and discuss new technologies such as optical/electrical interconnect in data centers, co-packaging optics (CPO), advanced modulation, signal processing, and coding.
