Title: 400G – don’t get confused with this transceiver generation
Presenter: Thomas Weible, Flexoptix
Abstract: Transmission speed of 400G is becoming a reality, with new challenges for optical and electrical components in high speed systems emerging as well. PAM4 modulation is one key component for 400G transmission with transceivers, this talk will be a show and tell into PAM4. With this knowledge, the design decisions behind the new formfactors OSFP, QSFP-DD, SFP56-DD and µQSFP are easier to understand. This talk will help you to: * Design / build new kind of applications or connections with your networking gear in the field * Avoid pitfalls when designing your racks * Be aware how power consumption and new plugs will be part of the new world of 400G transceivers.
