Keysight is driving the next stage of high-speed data innovation by enabling early R&D for 448 Gbps transmission. During this phase, experts are evaluating various modulation schemes like PAM4, PAM6, and PAM8. The industry’s adoption of PAM4 for 224 Gbps optical transmission underscores its commitment to pushing performance boundaries. Keysight demonstrates 224 GBaud PAM4 technology, achieving 448 Gbps per lane paving the way for energy-efficient 3.2T interfaces in data center networks. This achievement represents a significant leap forward in achieving higher data rates and improved signal integrity.
