The adoption of optical and electrical PAM4 technology goes mainstream with the 400G/200G/100G/50G Ethernet standards in 802.3bs and 802.3cd.  The characterization, compliance and troubleshooting of signals in these PAM4 standards are very different from earlier NRZ PAM2-based standards.  During this session, designers and test engineers will learn how to make the measurements needed in the optical PHY Layer including TDECQ evaluation techniques.

Cost: Free, but registration is required.

Lunch will be provided.
