The appeal of 400G Ethernet is clear: Bandwidth demand continues to grow fueled by new AI/ML applications, faster CPUs, serverless compute and high-speed distributed flash storage. Upgrading datacenters from 100G to 400G provides the simplest, lowest power and most cost-effective way to continue to scale network performance.
400G Ethernet also introduces a number of new technologies that include:
- New optics media types, such as 400G-DR4, 400G-FR4, 400G-SR8 and 400G-2FR4
- A choice of two different form-factors: the OSFP and QSFP-DD
- New PAM-4 modulation schemes for electrical and optical I/O
- New fiber-plant choices – as well as options to re-use existing fiber infrastructure.
This webinar takes a detailed look at what’s involved in upgrading physical datacenter infrastructure to 400G, and how to choose the optics, cable and fiber-plant options to best suit your applications.
