The new 400G Ethernet standard is based for the first time on PAM4 signals rather than NRZ ones. While this choice brings numerous advantages, it also carries some peculiar testing needs with it. Forward Error Correction becomes mandatory and has an impact on how to monitor signal quality and links stability in field.
The need for 400GE to support the growth of mobile access services and deployment of 5G also requires capability to verify and monitor latency and service disruption with new and smaller tolerance.
This webinar will focus on introducing the key testing requirements and challenges (and how to solve them) when deploying 400G Ethernet in Metro and Core Networks.
