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.

We will discuss how to help designers and test engineers determine the most effective optical test strategies for 400G Optical Standards. During this session, engineers will learn how to make the measurements needed in the optical PHY Layer including TDECQ evaluation techniques.

Attendees will learn about:

  • Ethernet Networking Market Trends & Technologies
  • Standards and Where PAM2 & PAM4 Fits
  • Testing PAM4:
  • Mark Test – Rethinking Hit Ratios
  • What is TDEC and How Is TDECQ Different?
  • Tektronix’s Rx & Tx Solutions for PAM4

Who Should Attend:

  • Datacenter Networking Interface Engineers
  • Integrated Photonics Engineers
  • Photonics Engineers
  • Long Haul Communications Engineers
  • Optical Engineers and Optical Engineering Managers
  • Optical Research Scientists
