UKNOF42 - 400G - don't get confused with this transceiver generation & IEEE 802.3bs

Speaker: Mr Thomas Weible (Flexoptix GmbH)

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 following Ethernet IEEE 802.3bs, this talk will be a show and tell into PAM4. With this knowledge, the design decisions behind the new form factors 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

- 100G will no longer be the fast option for IXP interconnections soon DR, FR4 and LR4 at 400G will be available

- Avoid pitfalls when designing your racks

- Be aware how power consumption and new plugs will be part of the new world of 400G transceivers.
