Coherent Optics Unleashed: From 400ZR Success to 800ZR/LR Advancements and 1600ZR Kick-off

Wednesday, 27 March, 16:00 – 17:00

Theater I

Session Description
OIF's 400G coherent specification (OIF-400ZR-02.0) has been a resounding success for interoperability. It's time for an update on OIF's next two generations of coherent specifications (800ZR, 800LR, and 1600ZR). In this session, a panel of OIF experts will give an update on 800ZR and 800LR technical work as well as an early status on 1600ZR, reviewing trade-offs in optical system performance, latency, power, and innovations. These projects will create the next core network architecture based on coherent pluggable technology common in next-generation Cloud DCI and Telecom edge network interconnects.
